Paper Abstract

For coherent pumping of Fe:ZnSe and Fe:ZnMgSe lasers generating giant pulses in mid-infrared part of spectrum the radiation with wavelength ~ 3 μm and pulse-length in the range of hundreds of nanoseconds (for room temperature operation) are needed. For more flexibility in pumping of Fe-based mid-infrared materials also new Er:YSGG laser was designed and characterized and compared with previously designed Er:YAG laser. The giant pulses with the energy 53 mJ and length of pulse ~ 80 ns were obtained for pumping 24 J. The generated wavelength was measured to be 2.79 μm and space structure was close to Gaussian.
