I just found this thread, and I must say:

Totally AWESOME work! And such a great write-up with great photos!

Thank you so much for sharing! This is an epic thread.

Yes you have to be dedicated (or is it detonated? hehe) to keep plugging away! Many hobbyists throw in the towel after they cannot get ANY green at all. It's a lot harder than it looks. Goggles are definitely required around unmasked pumps though. It's fun learning along the way isn't it?

I was playing today with 808nm laser and some cheap crystals.
Here are some new pictures just to bump this topic.

Great thread. Helped explain to me exactly whats going on inside a cheap dpss pen, labby or any other green DPSS laser. I really enjoyed the read. I might give this a go myself but my mechanical skills are far behind my soldering skills

Wow, I never saw this thread before either. This should go into Sam's FAQ or something. Cool stuff!

This is the "down and dirty" part of the DPSS science. This should be stickied for all noobs to see when they ask HOW !!!!
Good work, pictures and descriptions.
