I am trying to build a driver for a SPL PL90 Laser Diode. I have done a lot of searching on square wave generators/oscillators and found a lot of different plans but can not find any information on how to build something to the specifications I need.
Power Output: 25W
Forward Current : 40A
Threshold Current: 1A
Operating Voltage : 4.3V
Rise/Fall Time: 1ns
Duty Cycle: .1%
Pulse Width: < 100ns
Frequency: I would like to use the highest constant frequency possible without causing damage to the LD. From what I understand around 1kHz is possible but anything over 10Hz should work.
Power Source: I'm using is a car battery charging off of an alternator so it will be about 13.5V. I know this wont be the most stable source but I think will be converting it down to 4.5V.
Most of the designs seem very similar to the example in the link below but I need to know the specific parts list to make mine work properly with that design or let me know if I completely wrong with my assumptions so far. I don't mind spending a little extra to get quality components but I don't waste any money on the wrong pieces.
I have completed 2 years of undergrad engineering course work (3 Physics, 3 Calculus, etc) before I decided to switch paths to medicine. So I have some understanding of the basics but I'm stuck with this project at the moment so any help would be greatly appreciated.
