A comprehensive resource for safe and responsible laser use

If you are being harassed by lasers

If you are being harassed by obvious lasers …

where you see someone holding a pen or flashlight-like object, and you can see the laser beam or laser "dot", contact local authorities or the police if necessary.

  • Simple harassment -- a beam on your skin or clothes -- is probably not punishable unless it continues, or unless it occurs during a critical situation such as driving.

  • A partial list of laser harassment incidents is here.

If you feel you're being harassed by non-obvious lasers …

first consider all the non-laser explanations for what you are experiencing. For example, plants can turn brown (see Letter #1 below) due to many factors other than laser beams.

Also, if you feel heat spots, consult your doctor or do an Internet search since there can be medical conditions that cause localized and/or intermittent feelings of being hot.

If you think there are beams, try blocking them. Visible laser light can be blocked by anything that also blocks conventional light, such as a solid curtain a wall or even a sheet of paper. Non-visible beams might possibly be blocked by metal objects such as aluminum foil or a baking sheet (hold the sheet over the area where you are having heat or pain, to see if it goes away).

If you really want to pursue this, get photographic and/or video evidence if at all possible. Ideally this would be pictures of the beams or the laser "dot", and also pictures of any damage.

If the harassment is mysterious or well-organized

Occasionally we get emails or calls from people who are sure they are being deliberately targeted over a long period of time, by angry neighbors or agencies such as the CIA. They clearly feel effects, but their symptoms are often inexplicable by normal means. For example, laser beams have gone through solid walls and they can feel heat on their skin.

At LaserPointerSafety.com, we are not experts in any directed energy. We are only experts in visible lasers. The light from visible lasers can be seen with the eye and can be recorded by a camera. A visible laser’s light can be blocked by a solid curtain or a wall.

Beyond that, we do not have expertise about non-visible lasers or directed energy devices.

Mysterious attacks in Cuba — a device or a "shared functional disorder"?

Persons who feel they have been targeted by mysterious enemies with directed energy devices may want to consider the case of the U.S. diplomats in Cuba.

In August 2017, reports came out that at least 16 U.S. diplomats serving in Cuba had been affected by mysterious “acoustic attacks.” Symptoms included hearing a buzzing sound, having headaches, hearing loss, balance issues and nausea. CBS News reported “mild traumatic brain injuries and possible damage to the central nervous system as a result of the attacks.”

The question is whether Cuba targeted diplomats with an actual device, or whether this may have been "mass hysteria." According to a report in Newsweek:

“Mass hysteria is the rapid spread of illness symptoms for which there is no organic cause,” [Robert] Bartholomew [author of a book on the topic] told Newsweek. “It happens in normal, healthy people—it’s not just ‘all in their heads’ because they do experience symptoms.”

Jon Stone, a neurologist from the University of Edinburgh first consulted for
the Guardian article, agrees. “To consider this diagnostic possibility properly you have to strip away its negative connotations. The symptoms experienced in outbreaks of ‘mass hysteria’ are genuine and not faked or imaginary,” he told Newsweek.

Stone argues that the term "mass hysteria" itself sounds sensational and far-fetched. In reality, it is not as uncommon as you might think. He explains: “‘Mass hysteria’ is so laden with negativity, it badly distorts its own case. It suggests shrieking and raving individuals—not hard-working and normal people who mostly get functional disorders in everyday practice.”

A better, less stigmatizing term, says Stone, is “share functional disorder.” He defines the condition as
a genuinely experienced illness, “in which there is some disturbance of bodily functioning which conventional diagnostic techniques fail to register.”

Why would ordinary citizens be targeted?

It seems unlikely that directed energy devices would be available or affordable to ordinary persons who want to harass other persons. Or whether such devices would be used by the government against ordinary citizens who don’t have vital state secrets.

We cannot help with issues about non-visible lasers or directed energy devices. However, below are some resources which may be of interest to persons who feel they are deliberately targeted by mysterious devices.

Links about covert harassment and directed energy weapons

The first two resources have links to other websites, organizations and videos of interest (too many links to list here). Thanks to Jeannie for her help with this list.

  • People Against Covert Torture & Surveillance, International From their home page: “PACTS, International is a support network for those targeted with organized stalking and remote electronic assaults, also known as electronic harassment. Electronic harassment in this context refers to the use of radio frequencies and other methods to remotely access a person's mind and/or body to gain control of the individual or group of persons.” Much of the information at their site is in links to their newsletter, such as this newsletter page.

Some cases and our response

Here is a case in 2018 of a visible green laser harassing homeowners at least five times over two weeks. The laser can easily be seen coming from a known location. But because it is the common-area hallway of an apartment, the perpetrator was not known.

Below are some sample reports of mysterious use of lasers, or suspected lasers, along with our responses. This information may help others in similar situations.

Letter #1: Laser harassment 24/7

We live across the street from a neighbor who has her laser lights on 24 hrs/7days a week. She shines her laser lights in other neighbors faces, heads, at children, family pets, windows of houses, plants and trees (which are singed from being over exposed/burned by laser lights), aircraft, on our parked vehicles, & vehicles driving down the street. When I have been in the front yard my eyes and face start burning from the lasering. The police have been called several times, but state that they cannot do anything.

Here are pictures of the laser attacks:



Do you have any suggestions on how to go about getting this individual to stop harassing & terrorizing us?

Our response:

You described your eyes and face burning when in your front yard. It would take a very powerful and expensive laser to do this. A simple laser pointer would not be able to create heat on your skin at a long distance such as across a yard. The most powerful handheld laser currently available [summer 2010] is the 1-watt Wicked Laser Arctic. It can burn skin but at a very close distance, and the burn is very small such as the size of a pea or less.

You also stated that various surfaces were singed. Again, it would take a very, very powerful and VERY expensive laser to do this. It is very hard to imagine any use outside of military or police (riot control), and even these are exceedingly rare.

One way to tell if a laser is being used against you is to see if it only happens when you are in line with a window or similar opening to the outdoors. This is because walls will stop laser beams, but windows can let light through. (Of course, windows also let through sunlight and heat (infrared), so just being warm next to a window can be caused by normal, non-laser reasons.)

Both photos that you sent have a vertical line that goes through a strong light in the photo. This straight line is NOT a laser. It is an artifact of how some digital cameras work. If there is a light source that is too strong for the camera's digital chip, then all pixels in the same vertical line will be overwhelmed. This is called blooming. You can read more about blooming here.

One question I have for you is whether you have seen laser beams with your own eyes (not from a camera's video). I am guessing the answer is "no".

I do not want to say absolutely, positively 100% that there is no laser activity from your neighbor's house. The world is very large, and every now and then there are strange things. However, I am 99.999% sure that there is no laser activity from your neighbor's house. Certainly the photos you have sent depict the blooming effect that is very common on some digital camera chips. There is no doubt that what is in the photos is NOT laser. The other effects you state, such as heating and singeing, are highly, extremely unlikely to be caused by any type of laser that a residential person would have access to or could afford.

Letter #2: Lasers cause pinpoint holes

To whom it may concern:

I have been getting burned for now about a year. I have been finding burn holes in my mini-blinds. My dog I have found burn holes on her skin also, Is there anything I can do ? It is really painful and I think they did this so I had to sell my home because I felt that my life was in danger I would be walking in the house and then I would get this burning sensation in my eyes and then I would fell my arms would be burning didn't matter what side of the house I was at I would get burned, I would tell people and they would say that's weird.

So I sold my home because I feel they chased me out by hurting me and my dog. I think they even killed some kittens with this laser flashlight. I am writing to you cause no one help me or those kitten that didn't make or had a chance, I think there should be a law against this it is really scary and painful. Thank you for having this information on the internet and maybe it can help someone.

Our response:

It is very difficult to use a laser to create holes at long range (more than a few yards or meters). It also requires a very expensive laser, to have enough power to make holes at long range. I would not know why someone would go to this trouble.

If what you are seeing is small, pinpoint holes, it is highly unlikely that these are from a laser aimed at a distance. Laser beams do spread out, even a little bit. For example, the beam at the aperture (output opening) of a powerful laser might be very small. This might be a few millimeters or up to 1/4" in diameters, and the edge of the hole would be sharp. At a house-to-house distance, the hole might be the size of a quarter at least, and the edges might be more ragged, with burn or scorch marks around the hole.

If a person is walking around with a hand-held laser (laser pointer or battery-powered laser), then they could get close enough to make small holes or burn marks. For a laser pointer, this takes a LOT of power and is expensive. I do not know why someone would do this. (If they wanted to cause trouble, there are a lot of ways that are more effective, much less expensive, and also hard-to-trace.)

It is possible for the laser beam to be invisible to our eyes. Infrared lasers have beams which we can't normally see. However, you can use a camcorder to try to see these beams. To try this, point the camcorder at an infrared remote control, which are very common for TVs, etc. When you press a button on the remote control, you should see a light flash in the camcorder viewfinder (but not with your eyes). If your camcorder can see the infrared light, then you should be able to see infrared laser beams using the camcorder's viewfinder or fold-out monitor.

If someone is using a laser in the way you describe, this is illegal. It is damaging your property, cruelty to animals, and assault & battery. You could call the police -- but you should be sure that you really do have evidence.

For your own sensations of burning, you may also want to consult a doctor or do research on the Internet. There are some conditions where you may experience burning due to something internal in your body.

Letter #3: Some suggestions from a person saying they were harassed

To whom it may concern:

When I read the two stories of people getting harassed by laser pointers, I thought I was reading about my own story.

I was also getting harassed by our neighbor. We complained to the police as well, but we got no help. Both me and my husband saw the green dots, still the authorities were not convinced. It's very difficult to film, since he changed locations from the window and could see us if we try to film or take picture. We finally moved from there and thought it would be over but to our dismay it continued in the second home. We moved in the same area, it was not far enough.

So, I started to do the research about laser pointers and their health risks on people. Here are a couple of suggestions: First, go to your Home Depot or Lowes and get a mirrored privacy film and stick it to your windows. Make sure your windows are completely covered. This will at least give you day time privacy and if they point the laser pointer at it they will get twice as much effect on themselves. Second, do not close your house completely. Leave your windows a crack open, because depending on the type of laser and its strength, all lasers emit radiation. The radiation further dries skin and increase the burning, and does not help in healing. Third, use coconut oil to moisturize skin. And, last, get as many humidifiers and run them until there is enough moisture in the house. This will negate the effects of radiation plus it will provide you with a relief from burning. I hope this helps. Good luck!

Finally, thank you for printing those articles, I thought I was alone. It is helpful to read what other people are going through.

Our response:

We have found a few people who, even if they moved to a different state, still said they had symptoms of being harassed by lasers. It is more likely that there is something about the person -- some medical or perhaps brain condition -- which is causing the symptoms. We urge such persons to get a medical exam and to stress to the doctor that you really are feeling these sensations (heat, etc.).

We are printing the information above because it may help others.

  • The first point is good. If a problem is being caused by visible light lasers, then light-blocking curtains, shades or films will eliminate the problem. You can also simply go into a room without windows or other openings to the outside, and see if the symptoms go away. Visible-light lasers, with a dot or beam that you can see, will be blocked by walls or other light-blocking material. It is theoretically possible that an infrared laser's energy might go through a lightweight material, but even here, putting a wall between you and a suspected laser source would block the infrared light.

  • The second point is not really accurate. Lasers do emit "radiation" -- electromagnetic radiation such as visible, infrared or ultraviolet light. Lasers available to the general public do not emit higher-energy nuclear radiation such as X-rays or gamma rays. Leaving windows open will not have any effect on light or radiation; for example, even a beam of X-rays will not somehow "build up" in a house.

  • The third and fourth points may help. If you do feel burning sensations, a cream or extra moisture in the air may well help.
