High-performance laser systems require gain materials with efficient pump absorption, excellent thermal management, and stable optical performance.

Yb:YAG (Ytterbium Doped Yttrium Aluminum Garnet) crystal is a promising laser-active material designed for diode-pumped solid-state laser applications.

Compared with traditional Nd:YAG crystals, Yb:YAG offers broader absorption bandwidth, longer upper laser level lifetime, and significantly lower thermal loading per unit pump power, making it suitable for high-power laser designs requiring improved efficiency and thermal stability.

CASTECH Yb:YAG crystals feature high optical quality, high thermal conductivity, strong mechanical properties, and compatibility with reliable InGaAs diode pumping at 940 nm or 970 nm.

Available in rod, disk, and slab configurations with customized dimensions, CASTECH provides flexible crystal solutions for different laser system requirements.
