Hello, Im new to this forum but have always had a interest in electronics and lasers and wanted to try taking on a project. I wanted to ask what is the cheapest way to get into pulsed lasers like the one in this video. https://www.youtube.com/watch?v=JLti...sExnl1B-w&t=0s. Another question I have is I have seen some laser designs with mechanical q-switching how is it possible to get a pulsed laser out of a diode pumped laser? just turning the diode off and on? what is the speed limit on switching the diode (is it limited by the diode or the amount of energy needed for lazing)?
