Diffusion Bonded Composite Laser Crystal

Coupletech also provides a various of diffusion bonded Composite laser crystal, such as Nd:YVO4 + YVO4, YVO4 + Nd:YVO4 + YVO4, Nd:YAG + Cr:YAG, Yb:YAG +Cr:YAG, Nd:YAG + YAG crystal, etc. Diffusion-bonded Crystal technology is to make two orthree pieces of laser crystal with the same crystal substrate close together toform the optical cement at room temperature after a series of treatment, andthen heat-treated crystal to form a permanent bonded without the case of otherbinders, and thermal lens effect can be reduced by diffusion-boundedtechnology. Diffusion Bonded Crystals (composite laser rods) consist of one laser crystal and one or two undoped material. They`re combined by optical contact method and further bonded under high temperature. Diffusion Bonded Crystals can effectively decrease thermal lensing effect considerably, therefore it`s very suitable for high power laser applications.
