Diffusion Bonded Crystals are crystals consisting of two, three or more parts with different doping levels or different dopant, usually one laser crystal and one or two undoped crystals combined by optical contact and further bonded under high temperature. This innovative scheme reduces thermal lens effect of laser crystals, provides integral components to make compact lasers.

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
