We demonstrate stable continuous-wave operation of a Cr:forsterite laser pumped by a cw Nd:YAG laser at 288 K. We use no choppers to limit the duty cycle of the cw system. The proper adjustment of the pump- and cavity-mode overlap based on the <i>ABCD</i> concept simulation eliminates the output power decrease at the high-level pump power. An output power of 1.1 W and slope efficiency of 26% are derived.
