More info

Yb:CALGO (Ytterbium-Doped Calcium Lanthanum Gadolinium Aluminate) Crystal is a high-performance laser material with a unique tetragonal crystal structure, making it ideal for high-power, diode-pumped solid-state (DPSS) lasers. It is pumped at 979 nm and generates a 1050 nm emission with a polarization in the Theta direction, ensuring minimal quantum loss (as low as 1.5%) and enhancing the potential for generating ultrafast pulses. With an impressive thermal conductivity of 6.7 W/m·K, Yb:CALGO is well-suited for high-power applications where efficient heat dissipation is critical. Heeger Materials provides high-quality Yb:CALGO Crystal for advanced laser systems.
