Hi, a lot of members said I should post here first. I first got into lasing when I saw styropyros channel on youtube, and thought "that is cool", so after a bit of research I built my first laser: 100 mW green altoids tin. My second one is currently being built, and this community sure is helpful!

You are welcome. Come join the "laser groupies".

Best wishes with your second build. If you can, make a build thread, it's always great to see other people's work.

Lots of knowledge people here so don't be afraid to ask. Enjoy and welcome.
