Continuous wave room temperature operation in the Cr-forsterite laser

摘要

Stable continuous wave operation of a Cr-forsterite laser pumped by cw ND:YAG laser has been demonstrated at 288 K. No choppers were used to limit duty cycle of the cw system. The proper adjustment of the pump and cavity mode overlap eliminates the output power decrease at the high level pump power. The output power 1.1 W and slope efficiency 26 percent were derived.
