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

Ytterbium-doped Potassium Gadolinium Tungstate (Yb:KGd(WO₄)₂, Yb:KGW) crystal is an excellent laser gain material, boasting numerous advantages over the widely used Nd³⁺-doped materials. Its wide spectral emission band of 1023-1060 nm enables the generation of short laser pulses (picosecond or femtosecond level). The broad absorption band at 980 nm and highly absorbent pump radiation allow it to efficiently utilize diode laser pumping. Compared with YAG doped with Yb³⁺ ions, KGW crystal has a larger absorption cross-section, which reduces the minimum pump intensity required to achieve transparency in the quasi-two-level system of Yb.
