I have played with many of the high-power laser pointers over the years from various makers. The pointers are cool to play with because they can melt plastic and burn things, but they don’t they don’t look that cool. A geek has taken it upon himself to make his own pulse laser pistol and this is what those laser pointers should look like.
The gun is called the DIY Pulse Laser Gun and was built by Patrick Priebe. The builder says that the gun has a small pulse laser head with a kW-pulse of infrared coherent light. A single shot can punch through a razor blade, plastic, and 5mm thick Styrofoam when focused.
The range of the gun is 3M for dark surfaces and the shot will make a stinging flame and leave a 5mm stain behind. I bet it would burn your skin pretty well too. I don’t even want to think about what it would do to your eye. The gun is about 320mm long and weighs two pounds.
