摘要

利用白光脉冲光纤激光器发出的高强度、高定向性的白光，聚焦地照射水，可以产生定向的、多级的彩色干涉环，这就是相干彩虹.脉冲激光加热在水里产生了大小相仿的气泡，每个气泡成为散射源.强光导致了空间自相位调制效应，从而产生了相干彩虹.已经在多种液体中观测到了这种现象.

When the highly-intensive and highly-directional white light from pulsed fiber laser is focused into water, many directional and colorful rings, coherent rainbows, are observed. The laser generates bubbles with similar sizes in the water, which serve as scatters. The intensive light leads to spatial self-phase modulation and thus generates the coherent rainbows. Such a phenomenon has been observed in many kinds of liquids.
