Just finished building my first 520nm laser!
For parts I used the OSRAM PL520 laser diode, a micro boostdrive, the minisabre v2 host, g2 lens, and copper 3.8mm module. The minisabre is a sweet looking host, although it is a bit on the difficult side to work with.
I put everything together following the danfex tutorial, and set my micro boostdrive to 280mA. The "moment of truth" of powering this thing on for the first time was nerve racking! I popped in two AA batteries, pressed the button, and then I was delighted by the fact that I did not just build a $250 paperweight.
This color is very bright! The color is noticeably different than 532nm, but only slightly.
Here is the laser compared to a 532nm laser of similar power (Wicked Lasers Fusion)
It's crazy to believe that we have green laser diodes available to us now. When I first joined this forum all we had for laser diodes were from DVD burners. Then "SenKat GB diodes", followed by the 10mW 405nm, the open can reds, the 6x 405nm, the PHR-803T, the amazing 445nm, the high powered 635nm, the single mode 450nm and 635nm, and now this. This hobby has progressed so much in the time that I've been here! I can't even imagine what the hobbyists think that have been lasing since the ruby and gas lasers of several decades ago.
