| Abstract: | A single longitudinal mode (SLM) 486.1 nm blue pulsed laser was investigated by adopting a single-frequency distributed feedback laser (DFB) injected optical parametric oscillator (OPO) and optical parametric amplifier (OPA) structure, pumped by a 355 nm ultraviolet SLM laser at pulse repetition rate of 200 Hz. The maximum output pulse energy of 22.0 mJ was obtained from this injection seeded OPO/OPA system, corresponding to an energy extraction efficiency of 35.4% and a peak power of 3.73 MW. The central wavelength of output laser pulse was 486.134 nm, which was well matched to the H-β Fraunhofer line of solar spectrum, and the detected spectral linewidth was around 120 MHz.
