A laser burning a piece of paper. This is the Astra Gemini laser (specifically the Astra stage). The flashing you can see is pulses of laser light - the laser itself is around 1cm in diameter at this stage. You can hear a snap as the laser instantly burns a mark on the paper. When you’re there it sounds pretty loud. The firing end of the Gemini laser - further down the chain i’m told sounds more like a gunshot if you put a piece of paper in it, at that stage its much more powerful. I’m hoping to be able to experience that at some point.
