1.1mJ 532nm Q-Switched DPSS Laser






Wow that thing is sweeet, nice vid! The shark riding on top adds a nice touch too. Have you ever thought of popping that badboy off the bench, taking it outside & tried etching a smiley face or something on the moon?
 
So.. thats about 11 watts average power - pretty impressive :D


... and kudos for the shark!
 
Maybe I'm wrong, but numbers look weird to me. If it is 1.1 mJ and pulse is 10ns, we have 1.1x10E-3 J / 10E-8 s = 1.1x10E5 W = 110KW, not 11KW.
What's wrong?
 
Good catch magonegro. If the pulse was 10ns you would be right. I just pulled the test report on the laser. I figured out where the numbers came from. It's the rated output I posted and the pulse duration should have been 100ns. That's what happens when you edit video after midnight. The actual measurements are: 1.52mJ with a pulse width of 80ns at 10kHz, so it's really a 19kW pulse.

So, actually a 1.9W average power. Pretty good ;)

edit: My error. 1.52mJ x 10000 pulses/second = 15.2 Joules. So 15.2 Joules / 1second = 15.2 Watt Avg. Like Benm says forward here.
