论文摘要
我们基于分布式反馈激光二极管，在633 nm处提出一个紧凑的碘稳定激光系统。在$ 27 \ times 15 $ cm $^2 $的占地面内，该系统提供了5 mW的单模光纤稳定光稳定光。与代表一级频率标准的CS时钟相比，评估了其性能，并通过光频梳实现了SI单元Hz。使用最适合的吸收线，激光器的平均时间低于$ 10^{-10} $，平均时间超过10 s。在几个碘线上研究了性能，并开发了一个模型来描述不同线上观察到的稳定性。
We present a compact iodine-stabilized laser system at 633 nm, based on a distributed-feedback laser diode. Within a footprint of $27\times 15$ cm$^2$ the system provides 5 mW of frequency stabilized light from a single-mode fiber. Its performance was evaluated in comparison to Cs clocks representing primary frequency standards, realizing the SI unit Hz via an optical frequency comb. With the best suited absorption line the laser reaches a fractional frequency instability below $10^{-10}$ for averaging times above 10 s. The performance was investigated at several iodine lines and a model was developed to describe the observed stability on the different lines.
