Laser parameters of amplified beam are depending on seed-beam and pump channel. If any further assistance concerning your individual setup is needed, feel free to contact us.
Depending on the setup and applied power, thermal bonding of solid-state laser crystals plays a key role in achieving stable and high-performance amplification power. Due to our design concept and solder joining technology, a radial heat dissipation is achieved with exceptional homogeneity. After years of dedicated research and development for high-end laser beam sources supported by thermal simulations, we have innovated a distinctive approach for mounting and cooling solid-state laser crystals.
