标题： Experimental observation of self-frequency-shifting Raman quasi-solitons in a fiber Fabry-Perot resonator

摘要： 我们报道了在弱正常色散区域的脉冲泵浦高Q值光纤法布里-珀罗(FP)谐振腔中自频移拉曼准孤子的产生。它们是由四阶色散介导的调制不稳定性引起的，在拉曼增益超过腔损耗的条件下形成。所得光谱跨越超过50太赫兹，类似于在单通波导中产生的超连续谱。据我们所知，这是首次通过色散傅里叶变换实验明确识别此过程。此外，我们演示了通过调节泵浦重复率和腔往返时间之间的同步失配来抑制调制不稳定性，从而在这种系统中生成标准耗散克尔孤子。这些观察结果与基于广义Lugiato-Lefever方程的数值模拟高度一致，该方程包含了光纤的拉曼响应。 显示英文摘要

摘要： We report the generation of self-frequency-shifting Raman quasi-solitons in a pulse-pumped high-Q fiber Fabry-Perot resonator in the weak normal dispersion regime. They are induced by modulation instability mediated by fourth-order dispersion in a regime where the Raman gain overwhelms the cavity losses. The resulting spectrum, spanning over 50 THz, is reminiscent of the supercontinuum generated in single-pass waveguides. For the first time to our knowledge, we clearly identify this process using a dispersive Fourier transform experiment. Additionally, we demonstrate the suppression of modulation instability by tuning the synchronization mismatch between the pump repetition rate and the cavity roundtrip time, enabling the generation of a standard dissipative Kerr soliton in this system. These observations align remarkably well with numerical simulations based on a generalized Lugiato-Lefever equation, incorporating the Raman response of the optical fiber.
