The absorption<br>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<br>various applications<br>Lasers emitting at 1.5um are of great interest for several industrial applications. This interest is, first of all, due to eye-safety of 1.5um radiation. Other advantages of this wavelength are high transparency in atmosphere and<br>fused-silica wave guides and availability of sensitive room temperature light detectors(Ge and InGaAs photo<br>diodes).All this makes 1.5\u00ce\u00bcm lasers very attractive for applications in range-finder, environmental sensing,<br>telecommunications, surgery,etc. Co:Spinel absorption peak is close to 1520nm,which is most used in eye-safe laser.
