摘要:

作为超稳定脉冲训练源的锁模光纤激光器通过提供高峰值功率、高重复率、飞秒范围脉冲宽度和窄线宽而使广泛的基础和应用研究领域发生了革命性变化。然而,线宽变窄的进一步进展似乎受到载波包络相位控制的复杂性的限制。在这里,我们第一次从实验和理论上证明了一种新的共振矢量自锁模机制,其中调谐腔内双折射导致纵模边带的激发,并伴随着与相邻纵模的边带的共振相位锁定。与声学声子的额外谐振提供了重复率可调谐性和线宽缩小到Hz范围,这大大降低了载波包络相位控制的复杂性,因此将为在计量学,光谱学,微波光子学,天文学和电信应用中推进激光器开辟道路。

英文摘要:

A mode locked fibre laser as a source of ultra-stable pulse train has revolutionised a wide range of fundamental and applied research areas by offering high peak powers, high repetition rates, femtosecond range pulse widths and a narrow linewidth. However, further progress in linewidth narrowing seems to be limited by the complexity of the carrier-envelope phase control. Here for the first time we demonstrate experimentally and theoretically a new mechanism of resonance vector self-mode locking where tuning in-cavity birefringence leads to excitation of the longitudinal modes sidebands accompanied by the resonance phase locking of sidebands with the adjacent longitudinal modes. An additional resonance with acoustic phonons provides the repetition rate tunability and linewidth narrowing down to Hz range that drastically reduces the complexity of the carrier-envelope phase control and so will open the way to advance lasers in the context of applications in metrology, spectroscopy, microwave photonics, astronomy, and telecommunications.
