Pulsed YLF-Ho laser emission at 0.75 to 2.9 um

摘要

Abstract: The results of spectroscopic and laser studies of YLF-Ho crystals as the active media for multiwavelength lasers are reported here. The output energies for 0.75 $mu and 2.9 $mu laser wavelengths at room temperatures and flashlamp pumping were measured for the first time. The temperature dependence of the threshold pump energy for a wavelength region from 0.75 to 2.9 $mu was demonstrated. The influence of the concentration effects and the up-conversion processes on laser output under high pumping energy was studied. Output energies of 30 mJ and 46 mJ were obtained at 0.75 $mu and 2.95 $mu respectively.!
