Re: Questions about powerful lasers
Before you give up on lasers, think about this: high-enough rated goggles can reduce the transmission of that wavelength upwards of 10^6 times. That's reducing it by a factor of one MILLION.
If you want to do this, get a ~500-700mW 405nm laser, always keep your OD6+ goggles on (see these: YLW - Blu Ray, Blue Diode, 457nm [NR-YLW-EN207] - $101.50).
Even at 700mW of output power, if you got a reflection, the worst damage you could take would be from 700 NANOwatts of 405nm light. A lit room is brighter than that.
It's an expensive pair of safety goggles, but they are rated for use and you will be fine, most likely even from just looking straight into the laser (but still, DON'T DO THAT).
