【摘要】 通过使用美国通用扫描公司的扫描头控制BBO晶体的转动,用CCD对BBO-OPO输出波长进行标定,实现了BBO-OPO调谐系统的闭环控制,相对波长调谐误差小于0.04％,并给出了0.347μm泵浦Ⅰ类相位匹配BBO-OPO输出彼长随泵浦光入射角变化的理论和实验曲线.更多还原

【Abstract】 We realized closed loop control system of BBO optical parametric oscillation tuning system, by using American General Scanning Inc.’s controller to control BBO crystal’s rotation, and demarcated the output wavelength with charge coupled device (CCD). The system’s relative wavelength tuning error was less than 0.04%. We also demonstrated 0.347 μm pumped type Ⅰ phase matching BBO optical parametric oscillation’s theoretical and experimental curve of output wavelength versus pumped light incidence angle.更多还原
