520nm 1 watt Laser Build

[loreadarkshade]

My custom hand-built 520nm 1W pointer for a client.

One of my all time favorites, so bright and shimmery, even indoors with normal lighting! :O
These diodes are just insane.

You can buy one if you'd like to at my website: https://sites.google.com/view/ye-olde-laser-shoppe

Uses 2x 10440 batteries. Very low duty cycle.
