We have studied the generation of low-noise ultrashort multibound solitons in the telecommunication spectral window in an erbium-doped all-fiber ring laser with a highly-nonlinear resonator mode-locked by a nonlinear polarization evolution effect. The multibound soliton generation is obtained with more than 20 bound dechirped pulses with a duration of ~ 240 fs at a repetition rate of ~ 11.3 MHz (with a signal-to-noise ratio of ~ 73.3 dB), the relative intensity noise is <−140 dBc/Hz, and the Allan deviation of the repetition frequency does not exceed $\sim 1.3\cdot 10^{\mathbf {-8}}$ with a time averaging window of ~ 100 s.

具有高度非线性谐振腔的掺铒环形激光器中的多束缚孤子形成

我们研究了在掺铒全光纤环形激光器的电信光谱窗口中产生低噪声超短多束缚孤子，该激光器具有高度非线性谐振腔，通过非线性偏振演化效应锁模。多界孤子生成是通过超过 20 个持续时间为 240 fs、重复率为 ~ 11.3 MHz（信噪比为 ~ 73.3 dB）的绑定去啁啾脉冲获得的，相对强度噪声<- 140 dBc/Hz，并且重复频率的艾伦偏差不超过 $\sim 1.3\cdot 10^{\mathbf {-8}}$，时间平均窗口约为 100 s。
