A comprehensive resource for safe and responsible laser use
The technique is to look in the desired direction with the red aiming beams on, then to switch on the blue beams while looking at the desired target. The glasses have a lens that attenuates blue laser light, so that the user is protected in case of any reflected blue beams.
The two blue beams emitted from Priebe’s glasses, each roughly 1 watt, can burn cloth and pop balloons.
His inspiration: Cyclops’s 2-gigawatt “optic blast,” which is red in the Marvel comic books.
An online YouTube video shows Priebe’s laser glasses in action:
Due to the inherent danger of head-worn lasers, Priebe is not making additional glasses and he is not offering plans for others to build their own.
Priebe has previously built custom laser gadgets such as a replica of Iron Man’s palm-mounted repulsor ray projector, a laser “Gatling gun” with six rotating 1.4 watt blue beams, and a laser gun that emits a non-visible 1 megawatt pulse.

Hobbyist Patrick Priebe’s inspiration was the comic book character “Iron Man”, who has “repulsor rays” in the palms of his armor’s gloves. Priebe’s device is self-contained, with the battery in a case that wraps around the back of the hand. Simply flexing his hand triggers the beam to fire.

His inspiration: Iron Man’s repulsor ray glove, as seen here in the motion picture with Robert Downey, Jr.
Priebe made a number of versions. He is selling limited numbers (not mass-produced) of kits and assembled gloves on laser pointer forums for $200-500 depending on the version.

This differs from most pointers and handheld lasers, which use lasers that emit continuous light. This one emits a single, strong pulse each time the trigger is pulled. It is “enough to punch holes in plastic sheets, scorch wood, and pop balloons from several feet away” according to Dvice.com.
The maker, Patrick Priebe, posted a YouTube video showing the gun in action. He also was offering it for sale. According to Priebe, the gun uses a Q-switched Nd:YAG laser. It takes four seconds to charge the capacitor; the gun then fires a 100 nanosecond, 1 megawatt burst of infrared 1064 nanometer light. The gun took Priebe about 70 hours to build. His YouTube page offers to help others wanting to build their own laser gun.
SAFETY NOTE: Because the laser emits an invisible pulse, it would not be a visual interference hazard to aircraft (e.g., it could not cause glare or flashblindness). At close range the Q-switched pulse would definitely be an eye hazard, causing an explosive steam “pop” on the retina rather than the relatively slow burn of a continuous-wave laser. LaserPointerSafety.com has not done an analysis to determine the “safe” distance, beyond which it would not pose an eye hazard to pilots or others.
