Diffusion Bonding Laser Crystal

Diffusion bonded crystals consist of one laser crystal and one or two undoped material. They are combined by optical contact method and further bonded under high temperature. Diffusion Bonded Crystal helps to decrease thermal lens effect considerably of laser crystals, provides integral components to make compact lasers.

OST Photonics are able to supply various standard assembly and special customized bonding crystals.These diffusion bonded composite crystals have different wedge structures, Brewster angles, etc. It is used to effectively reduce the thermal effect of solid-state high-power lasers.


Applications of Diffusion Bonding Laser Crystal


  • Industrial laser;

  • Biomedical laser/Medical laser;

  • Beauty laser;

  • Laser Lidar

  • Laser ranger finder

  • High-power laser system etc.


Advantages of Diffusion Bonding Laser Crystal


  • To improve and enhance thermal the thermal performance;

  • Lower thermal lens effect of end surfaces.

  • Increase the output power of laser crystals


Diffusion Bonding Process of Diffusion Bonding Laser Crystal


  • Perfect optical contact between the crystals to be bonded;

  • Heating up of the two parts very slowly, to a very high temperature, probably 2/3 of the melt temperature or more, and exerting pressure to press the two parts together;

  • Keeping the bonded crystals for a certain period of time at this high temperature, so that diffusion takes place;

  • Slowly cooling the crystals (24 hours) down to room temperature.
