摘要

本文报道了一种基于π相移光纤布拉格光栅(π- fbg)和自注入锁模的超窄线宽光纤激光器，该激光器采用扫描相位掩模法将π- fbg刻在铒镱共掺光纤上。通过自注入锁紧，弛豫振荡频率(ROF)峰值从-103 dB/Hz降低到-128 dB/Hz，降低了约25 dB。激光的20 db线宽被抑制到500 Hz左右。

Ultra Narrow Linewidth Distributed Feedback Fiber Laser Based on Self-injection Locking

We have reported an ultra narrow linewidth fiber laser based on π phase-shift fiber Bragg grating (π-FBG) and self-injection locking, in which the π-FBG is inscribed on Erbium-ytterbium co-doped fiber with scanning phase mask method. Using self-injection locking, the relaxation oscillation frequency (ROF) peak was reduced about 25 dB from -103 dB/Hz to -128 dB/Hz. The 20-dB linewidth of the laser was suppressed to around 500 Hz.
