Abstract

A single-frequency diode-pumped Tm:YAG laser with continuous-wave emission at 2 μm has been developed. A throughout characterization in both multi- and single-longitudinal mode regimes has been performed by experimentally determining the corresponding threshold and slope efficiency values. Continuous-wave output powers of more than 70 mW have been obtained in single longitudinal mode operation near the room temperature. Very recently, a new pump diode with higher brightness was successfully employed to pump the laser cavity, and significantly increased laser performance has been achieved
