U-photonics
Material and Specifications - Doping Concentration: Yb: 5~15 at% Materials and Specifications - Wavefront Distortion: ≤0.125λ/Inch Materials and Specifications - Extinction Ratio: ≥28 dB
Yb:YAG is a promising solid-state laser medium particularly suited to diode pumping compared with traditional Nd-doped systems. Its broader absorption bandwidth than Nd:YAG reduces diode-laser temperature-management requirements. Upper-state lifetime is longer, and thermal load per unit pump power is stated as 3–4 times lower. Yb:YAG at 1030nm can replace Nd:YAG at 1064nm, while its 515nm second harmonic can replace 514nm argon-ion lasers.

Cr⁴⁺:YAG is an excellent passive-Q-switch crystal for Nd:YAG, Nd:YLF, Nd:YVO4 and other Nd- or Yb-doped lasers operating at 0.8–1.2μm. A passive Q-switch or saturable absorber provides substantial pulses without an electro-optic switch. Good chemical stability, durability, UV resistance, thermal conductivity, high damage threshold (>500MW/cm²) and easy handling make it a strong option for 1um Nd lasers, described as replacing conventional LiF and dyes in passive Q-switching.
