  Cr GSGG crystal to provide Q-switched operation of the ruby laser – CRYLINK CLICK HERE Cr GSGG crystal (Cr doped Gadolinium scandium gallium garnet) is a laser material with high efficiency. An electro-optic shutter element was first utilized to provide Q-switched operation of the ruby laser. Passive Q-switched ruby lasers were achieved with saturable dye absorbers and colored glass (compounds of selenium and cadmium sulfide. Recently the operational characteristics of a dye Q-switch for a pulsed ruby laser was still studied for application in underwater holography. However, the dye Q-switch was limited in durability because of degradation (decomposition) of the dyes and the glass Q-switch was readily damaged. Thus, the tetravalent chromium doped gadolinium scandium gallium garnet Gd3Sc2Ga3O12 (Cr4+: GSGG) passive Q-switch ruby laser-offers for the first time high reliability, durability and high efficiency.

 Co spinel for the passive Q-switching of solid-state lasers operating at eye-safe  1.5 μm - CRYLINK Co:Spinel (Cobalt-doped magnesium aluminate spinel; Co:MgAl2O4) allows the generation of short nanosecond pulse with high peak power around the eye-safe wavelength of 1.5um,perfect for telemetry applications. The absorption spectrum of Co2+-doped MgAl2O4 exhibited a broad absorption band in the wavelength range of 1200–1600 nm, which indicated that Co2+ ions substituted for the tetrahedrally coordinated Mg2+ ions in the MgAl2O4 lattice. Passive Q-switching of solid-state lasers with solid-state saturable absorbers is a very attractive Q-switching technique because it allows to develop compact and low cost laser sources of nano and sub nanosecond pulses far various applications.
