摘要翻译：
本文提出了一种用于激光稳定系统的开放式、灵活的数字锁相环。它是在一个廉价和易于访问的基于FPGA的数字电子平台（Red Pitaya）上实现的，运行一个可定制的开源固件。基于PC的软件接口允许远程控制平台和优化环路参数。包括几个工具，以允许测量的数量感兴趣的顺利和迅速。为了展示该平台的能力，我们在一个400m美元的光纤链路上构建了一个光纤噪声消除器。噪声消除是在30$~kHz带宽内实现的，该带宽主要受驱动器引入的延迟和光纤链路上的往返传播的限制。我们测量了平台本身的总延迟$565$~ns，将理论上可实现的控制带宽限制在大约225kHz。

英文摘要：
  This paper presents an open and flexible digital phase lock loop optimized for laser stabilization systems. It is implemented on a cheap and easily accessible FPGA-based digital electronics platform (Red Pitaya) running a customizable open-source firmware. A PC-based software interface allows controlling the platform and optimizing the loop parameters remotely. Several tools are included to allow measurement of quantities of interest smoothly and rapidly. To demonstrate the platform's capabilities, we built a fiber noise canceler over a $400$~m fiber link. Noise cancellation was achieved over a $30$~kHz bandwidth, a value limited mainly by the delays introduced by the actuator and by the round-trip propagation over the fiber link. We measured a total latency of $565$~ns for the platform itself, limiting the theoretically achievable control bandwidth to approximately 225 kHz.
