We report a large normal dispersion erbium-doped fiber laser with self-similar pulse evolution in the gain fiber. The cavity is stabilized by the local nonlinear attractor in the gain fiber through the use of a narrow filter. Experimental results are accounted for by numerical simulations. This laser produces 3.5 nJ pulses, which can be dechirped to 70 fs with an external grating pair.
我们报道了一种在增益光纤中具有自相似脉冲演化的大正常色散掺铒光纤激光器。通过使用窄滤波器,腔通过增益光纤中的局部非线性吸引子稳定。实验结果通过数值模拟得到解释。该激光器产生 3.5 nJ 的脉冲,这些脉冲可以通过外部光栅对展宽到 70 fs。
