| 摘 要： | 研究了掺铒光纤环形腔激光器(EDFRL)的注入锁定现象,提出了一种实现可调谐的单纵模EDFRL波长及功率稳定的新方法,即利用注入锁定技术向法布里-珀罗可调滤波器结合复合腔结构的EDFRL腔内注入低功率的连续光,使某一纵模在注入连续光的基础上起振.这个纵模在对增益介质的竞争中可以稳定地占据优势,从而与注入信号发生锁定,实现激光器输出光谱的稳定.实验得到激光器在1527.4～1561.9 nm范围内波长可调,输出功率＞0.6 dBm,信噪比(SNR)＞43 dB;输出光波长与功率抖动分别＜0.01 nm和≤0.02 dB,且线宽约为1.4 kHz.

| Abstract: | The injection locking of an erbium-doped fiber ring laser(EDFRL)is studied,and a novel method to stabilize the wavelength and output power of tunable single-longitudinal-mode EDFRL with compound cavity structure is proposed and experimentally demonstrated.One of the longitudinal modes is stimulated by an injected continuous wave so that the mode is able to stabilize the system.An output power of >0.6dBm and an SNR of >43dB within the tuning range from 1527.4 to 1561.9nm can be achieved for this laser.A wavelength variation of less than 0.01nm,power fluctuation of less than 0.02dB,and linewidth of about 1.4kHz are also obtained. |
