Hey everyone! I am a new member of the LPF community, I had been looking at it for over a week just reading and learning before registering to the site. I really like how helpful everyone is here and I really hope to learn a lot more from everyone. My goal is to build my own 445nm (currently in progress) Thank you Survival Lasers and DTR for the awesome service and fast replies by the way, also to build either a 520nm or 532nm, 405nm and lastly a 635nm. Thank you and look forward to hearing more from the community!
