We present an all-fiber Q-switched single-frequency laser oscillator operating in the eye-safe region at 1950 nm. It is based on the stress-induced polarization modulation in a Tm-doped distributed Bragg reflector fiber laser. The laser emits Q-switched single-frequency laser pulses with a pulse repetition rate ranging from tens of hertz to hundreds of kilohertz and an average power of several milliwatts. Pulse duration and laser spectral linewidth have been characterized. This is, to our best knowledge, the first demonstration of a Q-switched single-frequency fiber laser near 2 microm.
我们提出了一种工作在 1950nm 人眼安全区域的全光纤 Q 开关单频激光振荡器。它基于掺铥分布式布拉格反射光纤激光器中的应力诱导偏振调制。该激光器以几十赫兹到几百千赫兹的脉冲重复率发射 Q 开关单频激光脉冲，平均功率可达几毫瓦。我们对脉冲持续时间和激光光谱线宽进行了特性分析。据我们所知，这是首次在 2 微米附近演示 Q 开关单频光纤激光器。
