This project is based on SPL PL90_3 laser diode. It's maximum pulsed optical power is 75W. It's wavelength is 905 nm. BE CAREFUL - THIS IS INVISIBLE LASER RADIATION, IT COULD BE DANGEROUS FOR YOUR EYES!
This value is my project is smaller because of smaller laser current (less that 20A in peak).
Approximate value of the pulse length is 20-30ns (at 16V).
The capacity of C17 is 20 nF that gives theoretical energy that it could store - 2,5 uJ.
Lasers energy conversion efficiency is near 30%, which mean that maximum optical energy of the single pulse is 0.75 uJ.
I had measured average power of the laser diode in 1 kHz mode (with optics installed). It was near 0.4 mW.
