Abstract

An efficient continuous wave (CW) laser-diode-pumped Nd-doped Ca3(NbGa)2xGa3O12 (CNGG) laser operating at 935nm is demonstrated by using a simple linear cavity for the first time to our knowledge. Output power up to 1.12W is obtained, corresponding to a slope efficiency of 7.1% and an optical-to-optical efficiency of 5.7%. The laser operates with the fundamental transverse mode when the output power is as high as 800mW. This laser provides a potential light source for differential absorption lidar in water vapor detection.
