Yb:YAG – Laser crystal

Ytterbium-doped yttrium aluminum garnet (Yb:YAG) crystal is one of the most promising laser-active materials, suitable for high-power diode-pumped lasers and other optical applications.

Yb:YAG crystals have an 18nm wide absorption band at 940nm, very low fractional heating (< 11%), very high slope efficiency (> 56%), high mechanical strength, and high thermal conductivity.            They are more suitable for diode-pumping than traditional Nd-doped systems: compared to Nd:YAG crystal, Yb:YAG has a longer upper-state lifetime and three to four times lower thermal loading per unit of pump power.

Altechna can offer Yb:YAG crystals with various doping concentrations and dimensions, as well as right angles and Brewster angle cuts, plus high-quality polishing. For right-angle cut crystals,            we make HR+HT and AR coatings. Coated thin-disk crystals are also available.
