Solid State Laser Assemblies
- Includes microchip lasers, zigzag slabs and planar waveguides
- Epoxy-free, optical bonding for high power handling ability
- Wide range of materials including YAG, Nd:YAG, SiC, CVD and sapphire
- Zero thickness bondline with no absorption or scattering
- Bonding processes for both coated and uncoated interfaces
These high-power bonded assemblies for solid-state lasers use Precision Photonics’ proprietary CADB® process to produce adhesive free, composite crystal, glass and ceramic structures. Ideal for high-power laser applications for LIDAR, defense and aerospace, materials processing and medical industries, these highly robust, epoxy-free devices can be fabricated in a variety of geometries (rods with end caps, zig zag slabs and thin disk lasers) and form factors from 1 mm to greater than 100 mm.
The CADB process is extremely strong and offers negligible scatter and absorptive losses at the interfaces ; it also works with both IBS coated and uncoated surfaces. Our ion beam sputtered coating technology can handle damage thresholds above 40 J/cm˛ with less than 2 ppm bulk absorption in the coatings, making them suitable for a wide variety of high power solid state lasers and laser gain media structures including microchip lasers and Q-switch lasers with Cr4+ absorbers.
Why is CADB® better than diffusion bonding and optical contacting?
The PPC CADB optical bonding technology is a “gentler” process than traditional diffusion bonding, working at much lower temperatures and without pressure. This allows us to offer solid state laser configurations with a much wider range of materials and with unique IBS coatings integrated into the assembly. Because of the proprietary chemical processing of the surfaces, it is also much more durable than standard optical contacting, resulting in robust, stable components that can be further polished or coated even after assembly.
