摘要

采用单频分布反馈激光器（DFB）注入光参量振荡器（OPO）和光参量放大器（OPA）结构，由355nm紫外SLM激光器以200 Hz脉冲重复频率泵浦，研究了单纵模（SLM） 486.1 nm蓝色脉冲激光器。该喷射种子OPO/OPA体系的最大输出脉冲能量为22.0 mJ，能量提取效率为35.4%，峰值功率为3.73 MW。输出激光脉冲的中心波长为486.134 nm，与太阳光谱的H-β弗劳恩霍夫谱线匹配良好，检测到的谱线宽度约为120 MHz。

Single longitudinal mode 486.1 nm wavelength laser generation from BBO-optical parametric amplifier system for ocean detection

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.
