Diffusion Bonded Crystal
Bonding (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.

UPT can supply various standard assembly types as follows:

Material

Doping concentration(atm) or Optical Density(cm-1)

Aperture (mm)
