Abstract
A flashlamp pumped Cr:Er:yttrium scandium gallium garnet (YSGG) laser in a simple Fabry–Perot-type resonator has been developed. The emission wavelength of at the laser is easily selected by a specially designed resonator with a dichroic coated mirror. Maximum output energy of with a slope efficiency of 0.167% has been achieved in the free-running regime. In the Q-switching regime using an IR-quartz shutter, a Q-switched pulse of , single-pulse energy of , and a slope efficiency of 0.064% have been achieved in mode. Good agreement between a proposed theoretical model and the experimental results is obtained. The optimal output on the emission Cr:Er:YSGG lasers is estimated by a theoretical simulation.
