论文摘要
我们使用基于甲氮化炮的紫罗兰激光二极管报告了干扰过滤器稳定的外部空腔二极管激光器。表面激活的粘结玻璃基板被用作CAT的眼睛输出耦合器，以抑制由于光学损害而导致的功率降解。从长期频率稳定测试的结果中，证明了大约一周的无模式操作。经过大约三个星期的连续运行，功率降解小于10 $ \％$。结果表明，这种干扰过滤器稳定的外部空腔二极管激光器对于实用和便携式量子技术（例如原子钟或原子干涉仪）的潜力。
We report on an interference-filter-stabilized external cavity diode laser using a gallium-nitride-based violet laser diode. Surface-activated-bonded glass substrates were employed as cat's eye output couplers in order to suppress power degradation due to optical damage. From the results of a long-term frequency-stabilization test, mode-hop-free operation for about one week was demonstrated. After a continuous operation of about three weeks, the power degradation was less than 10$\%$. The results show the potential of such interference-filter-stabilized external cavity diode lasers for practical and portable quantum technologies such as atomic clocks or atomic interferometers.
