I stumbled across this sticky and I know it is old and being very complete as to how hard it is to build these things and all. Are there any posts on how to do it and resources to where to get parts and help. What about a page about how to successfully build a huge multiwatt powerful system. I have a YAG head and I would like to build a green laser from that. but no resources to find out who made it where to get a power supply or how to build one. I have a large frame argon that has a broken tube in it. it's got a great resonator and great platform to construct something I wish there was a forum on here on how to build something huge and help with it some positive encouragement and all that. if there is such a place please let me know
