Diffusion-bonding Crystal

Diffusion Bonded Nd:YAG + YAG, Nd:YAG + Cr4+:YAG, Nd:YVO4 + YVO4 laser crystals are used for compact laser aplications. These Diffusion Bonded Crystals are combined by optical contact method and further bonded under high temperature. Diffusion Bonded Crystal helps to decrease thermal lensing effect considerably.
