This custom pulse laser gun is packed with a 1 Megawatt laser capable of destroying a multitude of materials. The 1 MW laser is able to be battery powered becuase it only pulses on for a fraction of a section to burn through plastic (and even wood) instantly.
The handmade pulse laser gun took 70 hours to build and has a brass and aluminum finish with a bit of plexiglass. At just 32 cm long, it’s compact and light enough to carry. The batteries can fire 50 shots on a single charge of its Li-ion batteries. While there aren’t any build details available, you can check out our other DIY laser projects for inspiration.
