Diffusion Bonded Crystals (DBC) are crystals consisting of two, three or more parts with different doping levels or different doping, usually one laser crystal and one or two undoped crystals combined by optical contact and further bonded under high temperature.
Advantages:
- Reduces thermal lens effect of laser crystals
- Provides integral components to make compact lasers
- Improve the laser performance and beam quality
- Conductive to the intergration of laser systems and access to large-size crystals
