摘要

An efficient continuous wave (CW) laser-diode-pumped Nd-doped Ca_(3)(NbGa)_(2-x)Ga_(3)O_(12) (CNGG) laser operating at 935 nm is demonstrated by using a simple linear cavity for the first time to our knowledge. Output power up to 1.12 W is obtained, corresponding to a slope efficiency of 7.1percent and an optical-to-optical efficiency of 5.7percent. The laser operates with the fundamental transverse mode when the output power is as high as 800 mW. This laser provides a potential light source for differential absorption lidar in water vapor detection.
