Igor refers to IgorT, he was probably the best when it comes to DIY portable lasers. Designed and built his own SMD drivers by hand, and designed his own heatsinks that allowed incredible duty cycles with even 8-12X diodes. There's a reason you've probably never seen one of his lasers for sale...
I'll second that holy crap! I remember maybe one or two posts from you when I first joined. I definitely enjoyed your YouTube videos of your monster lasers in action. Welcome back indeed! :beer:
