Micro-pulling-down grown Tm,Ho:GSAG crystal as laser gain medium
Original language description
We report on the spectroscopic and laser properties of a Tm,Ho:GSAG (gadolinium scandium aluminium garnet) crystal which was grown by the micro-pullingdown (μ-PD) method. The crystal, doped with 4 at.% of Tm3+ and 0.75 at.% of Ho3+, was characterized under diode pumping at 782 nm and 1688 nm, corresponding to both possible thulium excitation schemes. In the pulsed regime, slope efficiencies up to 27.8% (with 1688 nm pumping) were achieved, with maximum output power up to 170 mW. Continuous-wave lasing at 2.1 μm was also demonstrated for this pumping, reaching 151 mW output power with a slope efficiency of 12%. Using a birefringent filter, a broad tuning range of up to 138 nm was obtained. These findings confirm μ-PD grown Tm,Ho:GSAG as a promising gain medium for compact, efficient, and tunable solid-state lasers emitting radiation around 2.1 μm.
