Hi
I am new to the hobby-I've been reading about DPSS vs direct diodes and if I read correctly, the 532 nm are DPSS and get to 532 nm via 1064 nm infrared (which is also why cheap 532 nm put out an invisible infrared beam-no filter).
I have a 520 nm 1 Watt (Challenger 2( being built by Sanwu- as I understand it (could be wrong) 520 nm diodes are direct-not using 1064 and a 2X frequency (divider?). So my Eagle 6 OD 190-540 should suffice?
It will use a single 18650 battery (I already have a collection from "lesser lasers" (IE 303, and "1Watt Gatling host 532 nm"-which judging from it's weak burning is likely far less).
Am I mistaken in thinking the 520 nm are more efficient than the 532?
I assume (from reading) that the 532 nm "1 watt Gatling" is less than 150 mwatt. It will light a BLACK match head-when I make a focal point- at roughly 4-6 inches-in 10 seconds or so. I am guessing I should never do that again-without 1064 nm protection!
