摘要：

We report on the single-longitudinal-mode Tm:YAG laser with a volume Bragg grating pumped by laser diode at room temperature. The maximum SLM power of 142 mW was achieved under incident pump power of 3.22 W. The central wavelength was 2012.6 nm accords with the resonant wavelength of the VBG. Three cavity lengths were used to achieve high efficiency and clear spectrum. The maximum output power were measured to be 450.5, 451.4, and 457.3 mW at incident pump power of 3.22 W, corresponding to a slope efficiency of 17.1, 16.9, and 16.7% for the cavity length of 30, 40, and 50 mm, respectively. 40 mm cavity length having the cleanest spectrum among the three was used for SLM laser with one 1 mm F-P etalon inserted into the cavity.
