| Abstract: | We report on a continuous-wave Nd:YVO4 oscillator at 1342 nm based on the combination of a grown-together composite crystal YVO4/Nd:YVO4/YVO4 and the 888 nm diode-laser direct pumping for the first time. At the absorbed pump power of 102 W, a maximum average output power of 37.2 W at 1342 nm was obtained, corresponding to an optical-optical conversion efficiency of 36.5% and a high slope efficiency of 63.0%, respectively. To the best of our knowledge, this is the highest output power ever obtained for a 1342 nm Nd:YVO4 oscillator. |
