Experiments on Nanosecond Optical Parametric Generation for 486.0 nm in BBO Crystal

In this paper, an injection-seeded nanosecond optical parametric generation (OPG) using BBO crystal, which combines relatively low thresholds with a simple and compact configuration, was demonstrated. By seeding externally distributed feedback (DFB) diode laser at 1313 nm wavelength, pumped by 355 pulse, the maximum blue output power of 1.36 W rate 100 Hz linewidth less than 0.13 were obtained, to conversion efficiency 21.2%.
