Recently, there has been significant interest in the generation of coherent temporal solitons in optical microresonators. In this Letter, we present a demonstration of dissipative Kerr soliton generation in a microrod resonator using an auxiliary-laser-assisted thermal response control method. In addition, we are able to control the repetition rate of the soliton over a range of 200 kHz while maintaining the pump laser frequency, by applying external stress tuning. Through the precise control of the PZT voltage, we achieve a stability level of 3.9 × 10 for residual fluctuation of the repetition rate when averaged 1 s. Our platform offers precise tuning and locking capabilities for the repetition frequency of coherent mode-locked combs in microresonators. This advancement holds great potential for applications in spectroscopy and precision measurements.
最近，人们对在光学微谐振器中产生相干时间孤子产生了浓厚兴趣。在本信函中，我们展示了一种利用辅助激光辅助热响应控制方法在微棒谐振器中产生耗散克尔孤子的方法。此外，通过施加外部应力调谐，我们能够在保持泵浦激光频率不变的情况下，将孤子的重复频率控制在200 kHz范围内。通过精确控制压电陶瓷（PZT）电压，我们在平均1 s时实现了重复频率残余波动的稳定性水平达到3.9×10 。我们的平台为微谐振器中相干锁模梳的重复频率提供了精确调谐和锁定功能。这一进展在光谱学和精密测量应用中具有巨大潜力。
