摘要：

We report on an intra-cavity optical parametric oscillator (OPO) based on MgO-doped periodically poled lithium niobate (MgO:PPLN) crystal in-band pumped by a wavelength-locked 878.6 nm laser diode (LD). A narrow linewidth 2.1 mu m laser output is obtained by using a reflection volume Bragg grating (VBG). The stability of the resonator under high pump power and the spot mode matching of the parametric laser oscillation process are considered comprehensively to determine the optimal cavity parameters. In the experiment, a narrow linewidth of 2.1 mu m maximum output power of 4.7 W is obtained with the pulse duration of 8.55 ns, the linewidth of 1.89 nm at 80 kHz repetition rate, corresponding to the maximum optical-optical conversion efficiency of 11.6%.
