  • Diffusion Bonding Crystals are crystals consisting of two, three or more parts of different materials, where the constituent parts are combined through a process called diffusion bonding, that is, sticking the interfaces(the interfaces must be extremely flat) of optical crystals tightly together, and after further processing, to permanently bond the crystals as a whole without adding any adhesive. Diffusion Bonded Crystals largely reduce thermal lens effect of laser crystals, provides integral components to make compact lasers.
