| 摘 要： | 采用一对MgO:LiNbO_3角度调谐覆盖了红近外波段0.7～2.2μm,并配以自动波长扫描。文中分析了影响脉冲宽度与线宽的因素,与实验结果相吻合。脉宽<30ps,线宽～1nm(简并波长附近～10nm),单脉冲峰功率达MW级,参量光总能量转换效率达5.4％。

| Abstract: | Eesearch on automatic tuning picosecond parametric laser is reported. Using one couple of MgO:LiNbO3 for angle tuning, equiped with automatic wavelength scanning system, a picosecond tunable output ranging from 0.7～2.2μm is obtained. The temporal and spectral characteristics of the parametric pulse are discussed. Analysis fits well with the experimental results. Single pulse width of <30 ps and band width of ～1nm have been achieved over 1MW in peak power. The maximum overall conversion efficiency of energy is 5.4%. |
