摘要

拉曼激光器在原子物理学中至关重要，而便携式设备的发展对拉曼激光器的时分复用提出了要求。我们展示了一种在光学锁相环（OPLL）内对从属拉曼激光器进行千赫兹跳频的创新方法，该方法在原子重力计中得到了实际应用，在原子重力计中，OPLL 频繁地在近共振激光器和显著失谐的拉曼激光器之间切换。这种方法将快速、广泛跳频的优点与 OPLL 固有的低相位噪声相结合，在紧凑型激光系统中具有广泛的应用范围，有望推动便携式仪器的发展。

Gigahertz frequency hopping in an optical phase-locked loop for Raman lasers

Raman lasers are essential in atomic physics, and the development of portable devices has posed requirements for time-division multiplexing of Raman lasers. We demonstrate an innovative gigahertz frequency hopping approach of the slave Raman laser within an optical phase-locked loop (OPLL), which finds practical application in an atomic gravimeter, where the OPLL frequently switches between near-resonance lasers and significantly detuned Raman lasers. The method merges the advantages of rapid and extensive frequency hopping with the OPLL’s inherent low phase noise, and exhibits a versatile range of applications in compact laser systems, promising advancements in portable instruments.
