Abstract

This paper demonstrates the laser performance of Er: YSGG (Er3 + doping concentration of 35at.%) Solid-state lasers pumped by xenon lamps. We use three different pulse repetition frequencies to investigate the laser output of the laser, and obtain laser outputs with maximum output energies of 224.2mJ (1Hz), 361mJ (at 5Hz), and 269mJ (10Hz). The slope efficiency is 2.166 ‰, 5.099 ‰, and 5.406 ‰, the corresponding average output power is 111.527mW, 812.025mW and 1038.813mW. In addition, the same equipment was used to explore the laser performance of Cr, Er: YSGG (Cr-doped 2%, Er-doped 30%) solid lasers for comparative analysis. It was found that the laser performance of the dual-doped laser was superior and the output efficiency was higher. Therefore, the Er: YSGG crystal laser can achieve excellent mid-infrared laser output, and the selection of appropriate sensitizing ions can enhance its laser performance
