Yeah, it'd be better with a YAG, but one of the goals of this project is to remain low-cost, so I'm looking into alternatives.

Blue pump is used because much higher power diodes are available for much cheaper than for green. The pulsed pump is prefered over CW because for amplification of a pulse, only the pump that temporally overlaps the unamplified pulse will contribute to the gain, and the rest of the CW will simply...

Thank you. Yeah, the OP should have said picoseconds were optimal, but nanoseconds would work and be more realistic, but I goofed and wrote picoseconds twice. It has been edited to reflect my intentions.

I found a paper that does it with 650 nm diodes. The pulses they get are ~1 ns: http://www.elexp.com/Images/Speed_of_light_with_650nm_diode_laser.pdf But their currents and powers are much lower than those I would use. I'd like to run the NDB7A75 at full power for each pulse (3.4 A), but I'm not...

We will be using a Ti:Sapph crystal.

I have the 445 nm NDB7A75 laser diode, and I was hoping to use it in a regenerative amplifier, for which I need pulses. The pulses would optimally be picoseconds, but could be in the nanosecond range, and I would like to create the pulses by using a driver that outputs electrical pulses that...
