The maximum output power reaches 8.3 W when the incident pump power is 15.8 W, with 52.5% optical-to- optical conversion efficiency and 62.6% slope efficiency. A stable laser output at 2118.1 nm is achieved, with a linewidth less than 0.4 nm （full width at half maximum）. The beam quality factor is M2- 1.25, measured by the traveling knife-edge method.展开更多

The frequency-tuning range extends from 760 to 825 nm by rotating the birefringent filters. When the intracavity etalon is locked on tile oscillating frequency of the laser and the length of the resonator is scanned by the piezo- electric ceramics transducer, a maximal continuous frequency-tuning range of 15.3 GHz is realized. The obtained Ti：sapphire laser is successfully applied to scan the saturation absorption spectroscopy of D1 transitions of SrRb atoms around the wavelength of 794.97 nm.展开更多
文摘采用5 W激光二极管端面抽运Nd∶YAG晶体,通过设计合理的谐振腔膜系,再分别利用双折射滤波器和标准具获得单一谱线基频光,采用长度为10 mm的Ⅰ类临界相位匹配LBO晶体进行倍频,获得稳定的561 nm单谱线输出。理论分析了双折射滤波器和标准具抑制其他竞争谱线的过程,发现使用双折射滤波器可以获得更窄线宽的输出,而使用标准具获得的输出功率更高,理论与实验相符。在泵浦功率为4.8 W时,分别获得227 m W和254 m W的561 nm单谱线输出。斜效率分别为6%和6.68%。
