Hey guys im new here and new to lasers. Ive been reading and reading pages on the forum for the last 4 days, but just signed up today. Im planning on a build real soon. I have a list of parts ill post when i get home from work. There seems to be only one thing so far that i am unsure of. And that is "nm" ex. 405nm. and how it works with "ma" im pretty sure "ma" stands for milliamps? But I dont know what "nm" means and if the lower the number is better for burning power or if a higher number is. I have used the search a couple different times but it comes up with nothing. If someone could please fill me in it would be greatly appreciated.
