I was getting some laser engraving done by the nice people over at Trilogy Lasercraft, a nearby company. They showed me some of their machines in operation, and they’re great fun to watch. This was for another customer:
They cut and engrave lots of different materials, but paper and card form quite a big part of their business. The light that you see is not the laser, which is infrared and invisible. It’s the flaring of the paper particles that are burned off.
Wow! That is cool.
The laser in Bond films is always much slower…
Cool! Do they do tattoos as well? 😉
