I have a driver that can output 50A 5ns 20kHz pulses and want to use it to power a blue diode. However, I have a few questions which are hopefully cheaper and faster to ask rather than determine experimentally! 1. Is there any danger of facet damage from these short pulses? 2. Can I...

Hello. I'm on a steep learning curve trying to replace a portable but expensive 532nm Nd-YAG with a blue PLD... Not a traditional laser pointer but this seems to be where all the wisdom is!

Hi there. I'm toying with the idea of using a cheap blue/green diode to check my homemade submersible isn't heading towards anything that isn't water. Not a Lidar system, just measuring the reflected light. My back-of-envelope calculations suggest a 1-2W laser will give me a detectable...
