Diffusion Bonding Crystals are crystals consisting of two, three or more parts with different types, Bonding Crystals are often used to decrease thermal lens effect, that is conducive to the stability of lasers and high-power laser operation. This bonding technology in laser applications can not only greatly improve the laser performance and beam quality, but also conducive to the integration of laser systems and access to large-size crystal.
