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. HGO 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.

Descriptions
Diffusion Bonded Crystals largely reduce thermal lens effect of laser crystals, provides integral components to make compact lasers.
Diffusion bonding process:
1) Perfect optical contact between the crystals to be bonded;
2)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;
3) Keeping the bonded crystals for certain period of time at this high temperature, so that diffusion takes place;
4)Slowly cooling the crystals (24 hours) down to room temperature.
Product Serials:
1) YAG+Nd:YAG+ Cr4+:YAG; YAG+Nd:Ce:YAG+Cr4+:YAG; YAG+Yb:YAG+Cr4+:YAG
2)YVO4+ Nd:YVO4 + YVO4; GdVO4+ Nd:GdVO4 + GdVO4; YAG+Nd:YAG+ YAG
3) YLF+Nd:YLF+ YLF; YLF+Pr:YLF+ YLF
4) YAG+Ho:YAG+YAG; YAG+Tm:YAG+:YAG
5) Tisapphire+Tisapphire
Diffusion bonding for other crystal assambly types are also available.
Advantages:
1)To improve and enchance thermal the thermal performance;

KDP Potassium Dihydrogen Phosphate and KD*P or DKDP Potassium Dideuterium Phosphate are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low. They are usually used for doubling, tripling and quadrupling of a Nd:YAG laser under the room temperature. In addition, they are also excellent electro-optic crystals with high electro-optic coefficients, widely used as electro-optical modulators, such as Q-switches, Pockels Cells, etc.

Longpass filters are ideal for a variety of applications, such as gas monitoring, temperature, sensing, thermal imaging and motion sensing, etc. Longpass filters block shorter wavelengths and transmit longer wavelengths. Blocking can be from reflectance, absorption or a combination. Transmission in the pass band can be enhanced with an antireflection coating on the second surface.
