Cr-doped yttrium aluminum garnet (Cr:YAG) crystal QC series

cobalt-spinelopticalphotorefractive

Q-switch crystals serve an essential role in passive quality modulation within resonators. The intrinsic transmission characteristics of these crystals play a crucial role in determining the duration of the generated pulses. Ensuring a homogeneous material with precisely controlled doping level and thickness is of supreme importance to achieve the desired initial transmission values. Moreover, these crystals are equipped with anti-reflective (AR) coatings on both sides to optimize their performance. • Material : Cr:YAG, Co:Spinel • Dimensions tolerance : +/- 0.1 mm • Surface quality : 10-5 S-D • Surface flatness : λ/10 @ 633 nm • Parallelism error : < 20 arcsec • AR/AR coatings : R < 0.2 %
