Ho:YAG

Technical parameters

Ho-doped yttrium aluminum garnet Ho:YAG is promising material for tunable and ultra-short-pulse generating lasers, operating in 2.1 μm spectral region.
It can be advantageously resonantly pumped with Tm-based fiber lasers or laser diodes in broad absorption band peaking at 1907 nm. The low quantum defect of Ho:YAG makes the heat load small, and together with excellent thermomechanical properties of Ho:YAG it gives the potential for scaling to high output powers.
