Diffusion Bonding Crystal

Diffusion Bonding Crystal

These Diffusion Bonded composite crystals are used to effectively decrease heat effect of solid-State High-Power Laser

High damage threshold

Improve beam quality

Decrease thermal effect

Improve efficiency

Compact size

 

Composite laser rod is a crystal consisting of two ,three or more parts with different dopant level .Usually,doped and undoped material used.

Dopant level and rod configuration can vary as well as the number of parts. It can have different wedged structure,Brewster angles,etc.
