摘要

孤子爆炸是超快激光中亮耗散孤子(DS)的一种极端脉动行为。通过数值模拟，我们发现在爆炸过程中暗孤子(DAS)可以与亮孤子共存。爆炸孤子的坍缩时间结构是由das引起的。我们在明亮的DS中揭示了DASs的诞生、演化和衰变。对爆炸孤子的时频分析有助于我们更好地理解爆炸孤子的时间和光谱结构，这可能对孤子爆炸过程中同时存在的暗孤子和亮孤子的实时光谱分析有帮助。

Dark solitons in the exploding pulsation of the bright dissipative soliton in ultrafast fiber lasers.

Soliton explosion is an extremely pulsating behavior of the bright dissipative soliton (DS) in ultrafast lasers. By numerical simulation, we find that the dark soliton (DAS) can coexist with the bright soliton during the exploding process. The collapsed temporal structure of the exploding soliton is induced by the DASs. We reveal the birthing, evolving, and decaying of the DASs inside the bright DS. The time-frequency analysis of the exploding soliton helps us better understand the temporal and spectral structures of the exploding soliton, which might be useful for real-time spectroscopy of the coexisting dark and bright solitons during the soliton explosion.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
