Widely tunable continuous-wave Cr3+: LiSrAlF6 ring laser from 800 to 936 nm

摘要

We report on a widely tunable, diode-pumped, continuous-wave, single-frequency Cr3+:LiSrAlF6, laser with a novel double-ring cavity configuration. The optical diode and the tuning element were located in the ring subcavity to decrease their insertion loss. Using an 1800-lines/mm grating as the tuning element, we obtained a laser emission of 20-mW output power at 870 nm and a tuning range of from 800 to 936 nm. When we used a 1200-lines/mm grating with a higher diffraction efficiency, the laser had a slightly wider tuning range of from 800 to 938 nm. However, the output power decreased at this tuning range.
