Narrow-linewidth BaGa4Se7 optical parametric oscillator
文献摘要：
The linewidth of the BaGa4Se7[BGSe]optical parametric oscillator[OPO]was narrowed for the first time,to the best of our knowledge,by inserting a Fabry-Perot[FP]etalon into an L-shaped cavity.When a 15 mm long BGSe[56.3°,0°]was pumped by a 1064 nm laser,the peak wavelength was～3529nm,and the linewidth was 4.53 nm[3.64 cm-1]under type Ⅰ phase matching.After inserting a 350 μm thick FP etalon,the linewidth was decreased to 1.27-2.05 nm.When the tilt angle of the etalon was 2.34°,the linewidth was 2.05 nm[1.65 cm-1],and the peak wavelength was still～3529 nm.When the tilt angle of the etalon was 3.90°,the peak wavelength was 3534.9 nm,and the linewidth was 1.27 nm[1.02 cm-1],which was the narrowest linewidth of a BGSe OPO,to the best of our knowledge.The beam quality was also improved after inserting the FP etalon.
