I wonder how well the opthalmologist is doing. These guys are going to be paying him a visit playing around with those lasers and no PPE.

    Eh, I don't see the risk, no pun intended. It's not collimated, and it's not going to be in focus anywhere but on-target. It's also probably in the long-wave range >>1000 nm that's not focused by the eye. At the end of the day it's no different from any other source of spot heating. I get more nervous around some of the LED flashlights you can buy these days.

    I want one. Hot air blows.

      It's 45w of lasing power. I have a scar on my hand that's 15 years old from running one of those at 10% power and getting a reflection from a bare metal sheet.

      This will absolutely scar, if not char, your cornea faster than you can blink.

        That's (again) less energy than a flashlight puts out these days, so the beam had to be tightly focused in your case. That isn't how these things work.

        There is nothing special about "lasing power." It amounts to a 45-watt light bulb, nothing more and nothing less.
