我们描述了一种基于光纤的乙炔稳定激光系统，其中光耦合到自由空间仅通过乙炔电池。该系统使用电信网络中使用的标准组件构建，使得该方法易于实现。使用简单的共线泵浦探针几何结构，即使没有锁定放大器，也可以检测到乙炔的无多普勒光谱，当光谱排列中的光路长度抖动以消除光纤设置中不可避免存在的干扰时。在（nu1 + nu3）波段，利用三次谐波技术稳定了13 C2H2的5个不同跃迁，并利用光学频率梳发生器测量了绝对频率。结果与国际度量衡委员会（CIPM）推荐值一致。本文提出的消除干扰的方法也可以推广到其他类型的稳定激光器。
We describe a fiber-based acetylene-stabilized laser system in which light is coupled to free space only to pass through the acetylene cell. The system is constructed using standard components used in telecommunication networks, making the approach straightforward to implement. The Doppler-free spectrum of acetylene can be detected, even without a lock-in amplifier using simple collinear pump-probe geometry, when the length of the optical path in the spectroscopy arrangement is dithered to cancel interference that is inevitably present in a fiber-based setup. The laser was stabilized to five different transitions of 13 C2H2 at the (nu1 + nu3) band using the third-harmonic technique, and the absolute frequencies were measured with an optical frequency comb generator. All the results are in good agreement with the values recommended by the International Committee for Weights and Measures (CIPM). The method for canceling the interference presented here can conceivably be generalized to other types of stabilized lasers as well.
