Watt-level,green-pumped optical parametric oscillator based on periodically poled potassium titanyl phosphate with high extraction efficiency
文献摘要：
We report a compact,efficient optical parametric oscillator(OPO)based on a periodically poled potassium titanyl phosphate(PPKTP)crystal pumped by a 532 nm laser,which generated 1.51 W of average power at the signal wavelength of 709 nm with the pulse duration of～1.0 ns.The extraction efficiency was up to 59％.To the best of our knowledge,this is the first report on Watt-level green-pumped PPKTP-based singly resonant oscillator OPO(SRO-OPO).The precise build-up time of OPO was determined to be 1.6 ns benefiting from the characteristic of twin-peak pulse profile of pump beam.The spectrum width of the idler was also measured to be 4.2 nm with the central wavelength of 2134 nm at 0.2 nm spectral resolution of optical spectrum analyzer.In addition,the beam quality of M2＜1.9 of generated signal exhibits a good consistency with M2＜1.5 for the pump source.
