Diode-pumped, continuous-wave, single-mode, tunable Cr(3+):LiSrAlF(6) ring laser

We describe an all-solid-state, tunable, single-frequency, continuous-wave Cr(3+):LiSrAlF(6) ring laser. When pumped with 360 mW of power from a single laser diode the laser has tuning range from 814 to 892 nm and a free-running frequency stability relative to a reference cavity of 60 kHz rms. Further stabilization promises to be possible by use of standard servo electronics. We demonstrate the use of the laser by performing Dopplerfree saturation spectroscopy of the cesium D2 line.
