非线性光学腔中的非高斯统计和极端波

Non-Gaussian statistics and extreme waves in a nonlinear optical cavity

A. Montina, U. Bortolozzo, S. Residori, F. T. Arecchi

摘要:

利用液晶光阀将泵浦光与近球形腔的模式耦合,构成单向光振荡器。对于足够高的泵浦强度,腔场呈现出复杂的时空动力学,伴随着极端波的发射和高斯统计的大偏差。我们确定了空间对称性破缺的机制,由于超循环型放大通过非局域耦合的腔场。

英文摘要:

A unidirectional optical oscillator is built by using a liquid crystal light-valve that couples a pump beam with the modes of a nearly spherical cavity. For sufficiently high pump intensity, the cavity field presents a complex spatio-temporal dynamics, accompanied by the emission of extreme waves and large deviations from the Gaussian statistics. We identify a mechanism of spatial symmetry breaking, due to a hypercycle-type amplification through the nonlocal coupling of the cavity field.
