| 摘 要： | 为了解决双波长激光器的稳定性问题、达到压窄双波长激光器线宽的目的，采用在激光器结构中加入环形滤波器的方法，抑制了不需要的振荡模式。对滤波器进行了计算和仿真，得到了梳状谱；通过实验得到了线宽为5.7kHz的单纵模双波长激光。经过输出功率稳定性测试，1h内功率波动为0.6dB。结果表明，环形滤波器的作用是十分明显的。

| Abstract: | In order to solve the problem of dual wavelength laser stability and achieve the purpose of narrowing the line width, the unwanted oscillation modes was limited by adding ring filter into the laser structure . After simulation and calculation of filter, the dressing spectrum was obtained. Single frequency dual-wavelength laser with linewidth of 5. 7kHz was obtained by experiments. After output power stability test, the power fluctuation within 1h was 0. 6dB. The result shows that the effect of ring filter is very obvious. |
