We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic range of 220 MHz are achieved, which leads to a strong robustness against large disturbances up to high frequencies. We demonstrate that serrodyne frequency shifting reaches a higher correction bandwidth and lower relative frequency noise level compared to a standard acousto-optical modulator based scheme. Our results allow us to consider promising applications in the absolute frequency stabilization of lasers on optical cavities.
我们报告了通过调频技术实现分布式反馈掺铒光纤激光器在光腔中的相对频率稳定。实现了 2.3MHz 的校正带宽和 220MHz 的动态范围，从而在高频下对大干扰具有很强的鲁棒性。我们证明，与基于标准声光调制器的方案相比，调频技术达到了更高的校正带宽和更低的相对频率噪声水平。我们的结果使我们能够考虑在光腔上对激光器进行绝对频率稳定的有前途的应用。
