First off let me tell you, this build was done by someone on LaserPointerForums named Minamoto Kobayashi and it seems like every build I have seen of his is stunning. You can see the original post here. Enjoy these amazing shots!
4W 450nm Cyperus IIIB laser build with a 20X Dioptika beam expander. I got his permission to host these builds of his on my website, and I must say they are some of the best most elegant laser build I have ever seen done! Scroll to the bottom to see what a SUPER collimated 450nm laser can really do.
