How to pulse a laser?

[Sigurthr]

Just keep in mind, as I've said elsewhere, when you use PWM to reduce brightness, you don't actually reduce the eye-hazard of the laser. If you're using a 20% duty cycle PWM on a 1W laser, and the LPM reads 200mW, it is still as dangerous as the full 1W, not the 200mW reading.

Looks good though!

Always good to keep in mind. Thanks for the warning. I'v always got my goggles close by
I didn't mean to down play the dangers by say it's not 2W powerhouse....just to make fun
