| 摘 要： | 利用琼斯矩阵对一种三环嵌套的无源谐振腔的选频特性进行了分析,并根据无源谐振腔选频的原理,设计了一种基于三环嵌套无源谐振腔的掺铒光纤激光器。实验结果表明:三环嵌套的无源谐振腔具有良好的选频特性,当泵浦功率为159 mW时,得到了稳定的单纵模激光信号输出;输出功率的最大波动为0.04 dB,输出中心波长最大漂移为0.016 nm;耦合器的耦合比减小时,激光器会处于多纵模振荡状态。

| Abstract: | The frequency-selecting characteristics of a triple-ring passive resonator are analyzed by Jones matrix,and an erbium-doped fiber laser based on the triple-ring passive resonator is designed according to the frequency-selecting theory of the passive resonators.The experimental results show that the triple-ring passive resonator has a good frequency-selection characteristic.When the pump power is 159 mW,the stable single-longitudinal-mode lasing signal is obtained.The maximum fluctuation of output power is 0.04 dB and the maximum variation of output wavelength is 0.016 nm.The coupling ratios of the optical couplers decrease,the laser will be in multi-longitudinal mode oscillation. |
