使用长（25公里）的光反馈环路，在具有Fabry-Perot配置的er光纤激光器中实现了高度的频率稳定性。在不平衡Mach-Zehnder干涉仪上观测时间条纹，确定频率漂移速率< 1 MHz/min。用延时自外差干涉仪测量的瞬时线宽小于3khz分辨率极限。在光学时域反射实验中，利用激光检测和定位施加在光纤上的时变相位扰动。
A high degree of frequency stability in an Er-fiber laser with the Fabry-Perot configuration was achieved using a long (25-km) optical-feedback loop. The frequency-drift rate was determined to be < 1 MHz/min by observing temporal fringes in an unbalanced Mach-Zehnder interferometer. Instantaneous linewidth measured with a delayed self-heterodyne interferometer was less than the 3-kHz resolution limit. The laser was utilized in an optical time-domain reflectometry experiment to detect and locate a time-varying phase perturbation applied to an optical fiber.
