Cr:YSO Crystal Description
Cr: Y2SiO5 (Cr:YSO) crystal is an effective saturable absorber Q switch for the ruby laser and the alexandrite laser. Experiments showed the Cr:YSO crystal can also be used to Q-switch the Cr:LiSrAlF (Cr:LiSAF) laser when the laser wavelength is at 880 nm.
Cr: Y2SiO5 (Cr:YSO) crystal is a pure tetravalent chromium system. The emission lifetime of Cr:YSO is 0.7 ms at room temperature, which is long compared with the duration of the Q-switched laser pulses. Therefore, Cr: YSO can be classified as a slowly relaxing saturable absorber.
