提出了一种利用外调制产生宽带窄线宽线性啁啾光的方法，并进行了实验验证。我们的啁啾光源是一个光循环移频环和光频率线性扫描器的组合。在200 GHz范围内产生了线性啁啾光，啁啾率为3.6×1016 Hz/s。啁啾光的瞬时线宽估计为小于50 kHz。
An external modulation method is proposed and experimentally demonstrated for the generation of linearly chirped light over broadband with narrow linewidth. Our chirped light source is a combination of an optical recirculating frequency shifter loop and an optical frequency linear sweeper. A linearly chirped light over a range of 200 GHz at a chirp rate of 3.6×1016 Hz/s is generated. The instantaneous linewidth of the chirped light is estimated to be less than 50 kHz.
