Sm:YAG–Excellent inhibition of ASE
Laser crystal Sm:YAG is composed of the rare earth elements yttrium (Y) and samarium (Sm), as well as aluminum (Al) and oxygen (O). The process of producing such crystals involves the preparation of materials and the growth of crystals. First, prepare the materials. This mixture is then placed in a high-temperature furnace and sintered under specific temperature and atmosphere conditions. Finally, the desired Sm:YAG crystal was obtained.

Crystal Bonding– Composite Technology Of Laser Crystals
Crystal bonding is a composite technology of laser crystals. Since most optical crystals have a high melting point, high temperature heat treatment is usually required to promote the mutual diffusion and fusion of molecules on the surface of two crystals that have undergone precise optical processing, and finally form a more stable chemical bond. , to achieve a real combination, so the crystal bonding technology is also called diffusion bonding technology (or thermal bonding technology).
