摘要：

We demonstrate the continuous wave p-polarized single longitudinal mode (SLM) operation of an Er: YAG laser at 1617.6nm pumped by a diode-laser with three inserted Fabry-Perot (FP) etalons at room temperature. The Brewster angle inserted FP is applied to obtain the p-polarized laser. For free running, the maximum output power is 570mW with a pump power of 12.5 W. An incident pump power of 12.5W is used to generate the maximum p-polarized single longitudinal mode output power of 78.5mW, corresponding to a slope efficiency of 1.6% and an optical-to-optical efficiency of 0.61%. The beam quality M-2 is measured to be 1.15 at the highest SLM output power. This stable polarized SLM oscillation is encouraging due to its application for an injection-locked system used as a master laser.
