Diffusion Bonded 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.This bonding technology in laser applications can not only greatly improve the laser performance and beam quatily, but also conducive to the intergration of laser systems and access to large-size crystal.
