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). -
