Crystal Bonding– Composite Technology Of Laser Crystals

The significance of the application of bonding technology on laser crystals lies in: 1.Miniaturization and integration of laser devices/systems, such as Nd:YAG/Cr:YAG bonding for the production of passive Q-switched microchip lasers; 2. Improving the thermal stability of laser rods Performance, such as YAG/Nd:YAG/YAG (that is, bonded with pure YAG to form the so-called "end cap" at both ends of the laser rod) can significantly reduce the temperature rise of the end face of the Nd:YAG rod when it is working, mainly used for semiconductor pumping Solid-state lasers and solid-state lasers that require high power operation.
Our company's current main YAG series bonded crystal products include: Nd:YAG and Cr4+:YAG bonded rods, Nd:YAG bonded with pure YAG at both ends, Yb:YAG and Cr4+:YAG bonded rods, etc.; diameters from Φ3 ~15mm, length (thickness) from 0.5~120mm, can also be processed into square strips or square sheets.
Bonded crystal is a product that combines a laser crystal with one or two pure non-doped homogeneous substrate materials through bonding technology to achieve a stable combination. Experiments show that bonding crystals can effectively reduce the temperature of laser crystals and reduce the influence of thermal lens effect caused by end face deformation.
