基于非线性偏振旋转技术，我们首次报道了一种稳定的23次谐波被动锁模掺铒光纤孤子激光器。在该激光器中，23个孤子同时均匀分布在腔中，并且所有孤子具有相同的能量和持续时间。耦合器输出功率的增加增强了色散辐射，腔长的增加增强了孤子与色散波的相互作用。这两个因素是产生23次谐波锁模运转的关键。
Based on the nonlinear polarization rotation technique, we report on a stable passive 23rd harmonic mode-locked erbium-doped fiber soliton laser for the first time to the best of our knowledge. In this laser, 23 solitons are uniformly distributed in the cavity simultaneously, and all solitons have the same energy and duration. The increase of the coupler output enhances the dispersive radiation, and the longer cavity strengthens the interaction between solitons and dispersive waves. The two above factors play the key function to generate the 23rd harmonic mode-locked operation.
