Quick, possibly stupid question.
I've been working on a LiDAR project and I need to either build or buy a driver capable of driving a LD with pulse widths near a few nS. I have found a driver that is capable of that however it has a drive voltage of 50-200V with a current range of 6-20A (I can post a link if requested, not sure if I was allowed to). I assume that LDs act differently at those short pulse times and so could high output LDs like the NUBM44 handle a 100V pulse for 2-3nS? I don't ever remember hearing of HV LDs but if they do exist that would be interesting to experiment with.
I guess the high voltage is needed to get the diode on as fast as possible. I will obviously test it with say an LED to see if it will pop one of those first before I instantly waste $100
Anyways, if anyone has any experience with high voltage, high frequency drivers and have some pointers, let me know!
