Cobalt-doped magnesium aluminate spinel (Co:MgAl2O4) allow 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 12001600 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
Co spinel——saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe wavelength of 1.5 m
Lasers emitting at 1.5m are of great interest for several industrial applications. This interest is, rst of all, due to eye-safety of 1.5-m radiation. Other advantages of this wavelength are high transparency in atmosphere and fused-silica wave guides and availability of sensitive room temperature light detectors(Ge and InGaAs photo diodes).All this makes 1.5m lasers very attractive for applications in range-finder, environmental sensing, telecommunications, surgery,etc. Co:Spinel absorption peak is close to 1520nm,which is most used in eye-safe laser. The absorption cross-section at 1520nm is 3.5×10-19cm2 and at 1331 is 2.8×10-19cm2,it has reported as Q-switch crystal for Er,Yb Glass and Nd:GYSGG,Nd:YALO3.
