There are more powerful DPSS handhelds, but they are not this small. The smallest 473nm handheld I can think of is the CNI CR2 which is not a very pretty host IMO. Plus this thing is waaaay more efficient.
Re: World's First Direct Diode 476nm Laser Pointer!
Awesome build! I would love to have one of these. No way I would even trust myself with a diode this expensive though. Hopefully many more of these get made and sold on the forum.
Finally a ~473 pen alternative to that UGLY CR2 host one. I would much rather have one that a bit less powerful in a nice AAA leadlight host, than have more power and have use crappy old CR2 batteries in what is probably the ugliest host of all.
