环形laser模型中单模和多纵模辐射的共存

Coexistence of single-mode and multi-longitudinal mode emission in the ring laser model

J. L. Font, R. Vilaseca, F. Prati, E. Roldan

摘要:

由于拉比分裂诱导增益的存在,在足够大的抽运长度和腔长下,均匀展宽的单向环形激光器可以产生多个纵模。这就是所谓的Risken-Nummedal-Graham-Haken(RNGH)不稳定性。我们数值研究的多模式解决方案的性质。我们表明,这种解决方案可以共存的单模之一,其稳定域可以扩展到泵值小于临界泵的RNGH不稳定性。Morevoer,我们表明,大泵浦值的多模解受两种不同的不稳定性的影响:一个干草叉分叉,它保留锁相,和一个霍普夫分叉,它破坏它。

英文摘要:

A homogeneously broadened unidirectonal ring laser can emit in several longitudinal modes for large enough pump and cavity length because of Rabi splitting induced gain. This is the so called Risken-Nummedal-Graham-Haken (RNGH) instability. We investigate numerically the properties of the multi-mode solution. We show that this solution can coexist with the single-mode one, and its stability domain can extend to pump values smaller than the critical pump of the RNGH instability. Morevoer, we show that the multi-mode solution for large pump values is affected by two different instabilities: a pitchfork bifurcation, which preserves phase-locking, and a Hopf bifurcation, which destroys it.
