OP0482 Ytterbium-doped Yttrium Aluminium Garnet (Yb:YAG)

Catalog No. OP0482
Surface Quality 10-5(MIL-O-13830A)
Perpendicularity ≤5′

Yb: YAG is an excellent laser-active material and more suitable for diode-pumping than the commonly used Nd-doped crystals. Compared with the traditional Nd: YAG crystal, Yb: YAG crystal has a much bigger absorption bandwidth to reduce the thermal management of diode lasers. Yb: YAG crystal is expected to replace Nd: YAG crystal for high power diode-pumped lasers and other potential applications.
