We propose a simple erbium-doped fiber laser configuration for obtaining multi-wavelength oscillation at room temperature, in which a few-mode fiber Bragg grating was used as the wavelength-selective component. An amplitude variation of 1.6 dB over 120 second period was obtained for three-wavelength oscillation at room temperature, which demonstrates stability of the output power. This multi-wavelength laser can be switched between dual- and triple-wavelength operations by properly adjusting polarization controller in the cavity. This multi-wavelength laser has the advantage of simple configuration, high stability, low cost and stable operation at room temperature.
我们提出了一种简单的掺铒光纤激光器配置，用于在室温下实现多波长振荡，其中使用少模光纤布拉格光栅作为波长选择组件。在室温下，三波长振荡在120秒周期内的幅度变化为1.6 dB，这证明了输出功率的稳定性。通过适当调整腔内的偏振控制器，这种多波长激光器可以在双波长和三波长操作之间切换。这种多波长激光器具有配置简单、稳定性高、成本低以及在室温下稳定运行的优点。
