Abstract

We report a diode pumped single frequency Tm:YAG laser with two coated fused silica etalons as mode selectors. The maximum single frequency output power was 681 mW with the pumping power of 4.83 W. The slope efficiency of single-frequency laser was 20.5% and the optical-to-optical conversion efficiency was 14.2%. According to the experimental results, we developed a prototype with the maximum single frequency output power of 249 mW and the slope efficiency of 23.1%. The frequency tuning was investigated by changing the temperature of the crystal. A tuning coefficient of 2.57 GHz/°C was obtained. The beam propagation factors M ² were measured as 1.01 in both directions. The linewidth of the single frequency was 40 kHz.
