Whatever refracts the light will have to stand up to the beam for long periods of time. Maybe it's a materials science problem.

- eru 2y agoAs long as it doesn't absorb the light, it's fine. Just like the electric cables for your water kettle typically don't get hot.
- queuebert 2y agoYour kettle's power cable is sized to handle the relatively tiny current put into it, but even then it does warm up slightly. Try to run a million amps through it, and it will vaporize. This type of laser carries so much energy that even a tiny fraction of a percent absorption will add up quickly, hence the propensity for injury.
