Diffusion Bonding Crystals are crystals consisting of two, three or more parts with different dopant levels. Usually,doped and undoped materials are used. difussion Bonded Crystals are used to decrease thermal lensing effect considerably.
Application:
Decrease thermal effect
improve efficiency
High damage threshold
improve beam quality
