Doping concentration 0.2-25 atm. % Wavefront distorton ≤λ/8 @ 633nm Extinction Ratio ≥28 dB Dimensional Tolerances Diameter: +0.0 mm/-0.05 mm, Length: +0.0 mm/-0.10 mm Dimensional Tolerances Length: ±1 mm Parallelism error ≤ 10 arcsec Perpendicularity ≤ 10 arcmin Flatness ≤λ/10 @ 633nm Surface Quality 10-5 S-D It is more suitable for diode-pumping than the traditional Nd-doped systems. It can be pumped at 0.94 μm laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.
