Hello everyone,
I am completely new to lasers and dont know a whole lot about them. I am very interested in the science behind them and want to learn how they work and what it takes to build them. I ordered parts to build a 1w 445 nm laser and should start that in a few weeks. I ordered the parts from DTR and survival laser and also ordered a good pair of goggles (OD4+ 190-540nm & 800-2000nm).
I will create another thread in the right section for when i build it. Could you guys guide me to some good books, videos, or articles i could read to get a better handle on the science behind lasers?

Glad i found this forum :thanks:

Also, i have been reading about IR filters and was wondering if i need to worry about that with my laser.

No, you don't need an IR filter for a 445nm laser. Only green 532nm and yellow 589/594nm lasers use those for the most part.

Welcome to LPF jallis11! :beer:
Looks like you off to a good start, glad to see that you've considered safety goggles before you build.

Take a look at "Sam's Laser FAQ" site for a lot of laser knowledge!

Have fun, be safe , and enjoy your stay here at LPF! :)

Just a quick tip about lenses. G2 lenses are for close up burning and engraving. 3 element lenses are for better beam shaping at the sacrifice of some burning power. This isnt all there is to it but worth mentioning to the newcomer. I thought the G2 was simple better since it was 3x the price. Thats just not how it works.
