Diffusion Bonding Laser Crystals
Diffusion Bonding Crystals are crystals consisting of two, three, or more parts with different types, Bonding Crystals are often used to decrease the thermal lens effect, which 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 is also be conducive to the integration of laser systems and access to large-size crystals.
