Experimental results of laser diode (LD) pumped monolithic non-planar ring resonator (NPRO) tunable single frequency lasers are reported. 1064 nm and 1319 nm lasers with the power of 1080 mW and 580 mW are obtained by LD pumped monolithic NPRO Nd∶YAG crystal, whose corresponding optical-optical efficiencies are 40.9% and 14.3%, respectively. The longitudinal mode and the linewidth of the lasers are measured using the scanning Fabry-Perot interferometer, which shows both of the two lasers are operating in single longitudinal and fundamental transverse mode, the linewidth of the two lasers are Δν1064 nm=41 MHz and Δν1319 nm=150 MHz, respectively. The beam quality of the two single frequency laser are measured by a beam quality analysis, which shows the beam quality factor are M21064 nm=1.14 and M21319 nm=1.15, respectively. The frequency tuning of the single frequency lasers are also studied by adjusting the temperature of the crystal. The maximal tuning range of 1064 nm laser is about 48.2 GHz with a average tuning coefficient of 1.42 GHz/℃; the maximal tuning range of 1319 nm laser is about 12.7 GHz with a average tuning coefficient of 1.42 GHz/℃.
