On page 211 of the Nov. 2007 Jameco catalog there is a 75W pulsed laser diode for what sounds like a quite reasonable price of $37.55. Has anyone here used one of these before? How did it perform?
For what use? 75 watts might be the peak power but at what pulse width and duty cycle? Average power is going to be orders of magnitude lower. The drivers for something like that are going to be tricky as well.
