介绍了一种灵活地产生激光冷却和原子干涉测量所需的光学频率的方法。它依靠光纤布拉格光栅技术对电光调制器的输出进行滤波，并在无对准、单种子、倍频的光纤激光器系统中得到了验证。该系统可在30 GHz范围内在40 ns内实现频率切换，输出功率0.5W，∼幅度调制，∼上升/下降时间15 ns，消光比超过80d B。该技术是实现量子技术的高带宽、移动工业和空间应用的理想选择。
A method for the agile generation of the optical frequencies required for laser cooling and atom interferometry of rubidium is demonstrated. It relies on fiber Bragg grating technology to filter the output of an electro-optic modulator and was demonstrated in an alignment-free, single-seed, frequency-doubled fiber laser system. The system was capable of frequency switching over a 30 GHz range in less than 40 ns, with ∼0.5W output power and amplitude modulation with a ∼15ns rise/fall time and an extinction ratio exceeding 80 dB. The technology is ideal for enabling high-bandwidth, mobile industrial, and space applications of quantum technologies.
