论文摘要
在这里，我们研究了被动室内光学过滤器的使用来控制极化模式的超快YTTERBIUM纤维激光器的激光输出光谱。随着滤波器截止频率的战略放置，可以增加或扩展总体激光带宽。研究了通过旋转过滤器调节的一系列截止频率的短通和长通滤波器，包括脉冲压缩和强度噪声，包括脉冲压缩和强度噪声。我们证明了腔内滤波器的使用不仅塑造了输出光谱，还为YB：纤维激光器中的整体宽带宽和较短的脉冲提供了一条途径。这些结果表明，光谱形状是常规实现YB中的45 FS脉冲持续时间的有用工具：纤维激光器。
Here we investigate the use of passive intracavity optical filters for controlling the laser output spectrum of a polarization-mode-locked, ultrafast Ytterbium fiber laser. With strategic placement of the filter cutoff frequency, the overall lasing bandwidth can be increased or extended. Overall laser performance, including pulse compression and intensity noise, is investigated for both shortpass and longpass filters with a range of cutoff frequencies, tuned by rotating the filters. We demonstrate the use of an intracavity filter not only shapes the output spectra, it provides a route for overall broader bandwidths and shorter pulses in Yb:fiber lasers. These results demonstrate that spectral shaping is a useful tool to routinely achieve sub-45 fs pulse durations in Yb:fiber lasers.
