IMG_20141012_085758.jpg

This is the Nd:YAG laser cavity i assembled and it have 50W output at 1066nm.

The pics are from YAG module, the heart of laser. The module have inside three 20W laser diode that pump a Nd:YAG rod , the module is assembled betwen two mirror mount with mirror 100% reflective behind and 80% to output as any laser. The module is powered by a driver and colled with a water chiller.
