【Abstract】 A high power mid-infrared PPLN single-resonant optical parametric oscillator(OPO)pumped by 1.06μm laser is proposed in the paper.The poling period of the PPLN is 29.1μm.If the OPO is pumped by a 1.06μm laser with the frequency,pulse width and power are 10 kHz,10ns and 34 W,respectively.The working temperature is 40℃.The output of the OPO will be a mid-infrared laser with a wavelength of 3.81μm.The average power and optical-to-optical conversion efficiency are up to 5.4Wand 15.88%,respectively.The results can be used in the design and investigation of mid-infrared laser.更多还原
