摘要

本文提出了一种采用主振荡器功率放大器结构的掺铒光纤激光器(EDFL)，该激光器采用电子反馈技术来降低强度和频率噪声。通过对泵浦二极管电流的反馈来抑制强度噪声，通过光纤干涉仪锁定激光发射并使用压电元件通过激光腔应变施加反馈信号来抑制频率噪声。

Frequency noise reduction in erbium doped fibre Bragg grating lasers using active electronic feedback

We present an erbium doped fibre laser (EDFL) in a MOPA (master oscillator power amplifier) configuration with intensity and frequency noise reduction using electronic feedback techniques. The intensity noise is suppressed using feedback to the pump diode current and the frequency noise is suppressed by locking the laser emission to a fibre interferometer and applying a feedback signal through laser cavity strain using a piezo-electric element.
