摘要:

光纤克尔谐振器是简单的驱动谐振器,具有期望的波长和重复率灵活性,用于产生超短脉冲,用于包括电信、生物医学和材料处理的应用。然而,迄今为止,光纤克尔谐振器通常产生更长的脉冲,并且需要比应用所期望的更复杂的技术来产生单脉冲。在这里,我们解决这些限制,展示了强大的单脉冲性能与120 fs的脉冲持续时间在光纤克尔谐振器的基础上拉伸脉冲孤子。通过匹配的数值和实验研究,发现展宽脉冲孤子的性能强烈地依赖于总腔长,和最佳长度被发现取决于驱动,拉曼散射,和总脉冲的拉伸。通过设计这种最佳的腔与所描述的设置,稳定的展宽脉冲孤子与120 fs的持续时间进行了实验观察。此外,孤子捕获证明了与脉冲驱动源,尽管大腔内呼吸和单脉冲性能观察。稳定的高性能单脉冲产生是实现实用飞秒脉冲产生的关键一步。

英文摘要:

Fiber Kerr resonators are simple driven resonators with desirable wavelength and repetition rate flexibility for generating ultrashort pulses for applications including telecommunications, biomedicine, and materials processing. However, fiber Kerr resonators to date often generate longer pulses and require more complicated techniques for generating single pulses than would be desirable for applications. Here we address these limits by demonstrating robust single-pulse performance with 120-fs pulse durations in fiber Kerr resonators based on stretched-pulse solitons. Through matching numerical and experimental studies, stretched-pulse soliton performance is found to strongly depend on the total cavity length, and the optimum length is found to depend on the drive, Raman scattering, and the total pulse stretching. By designing the cavity for this optimum with the described setup, stable stretched-pulse solitons with 120-fs duration are experimentally observed. In addition, soliton trapping is demonstrated with a pulsed drive source despite large intracavity breathing and single-pulse performance is observed. Robust with high performance single-pulse generation is a critical step toward useful femtosecond pulse generation.
