利用受激布里渊光散射和瑞利光散射在时间域内探测到气/液界面上的毛细波。气/水表面的受激布里渊散射信号表现出明显的振荡。它既不是纯正弦波，也不是纯余弦波，而是具有双重特征的。在1.4~2.0×10~6 m−1范围内，空气/正己醇表面有一个强烈的过抑制信号，而在低波数区域有微弱的振荡。这一振荡还表明存在两个浪。讨论了光热效应产生毛细管波的机理。
The capillary wave at air/liquid interfaces is detected by the forced Brillouin and Rayleigh light scattering in the time domain. The forced Brillouin scattering signal from the air/water surface shows clear oscillation. The wave is not pure sine or cosine wave but it shows dual features. A strongly overdamped signal is observed from the air/hexanol surface in 1.4–2.0×106 m−1, while the signal shows a trace of oscillation in a lower wave number region. The oscillation also indicates the existence of two waves. The mechanism to create the capillary wave by the photothermal effect is discussed.
