对短激光脉冲（持续时间为0.4 µs）照射下微米大小的水滴的畸变进行了波动光学计算。首先，我们发现电磁表面力，假设表面是静止的，此后，我们发现通过使用线性化的Navier-Stokes方程的失真。我们将运动描述为时间的函数，直到脉冲通过后22 µs。本研究推广了Lai [J. Opt. Soc. Am. B6，2430（1989）]的结果与张昌的实验[Opt.Lett.13，916（1988）]相吻合。
A wave optical calculation is made of the distortion of a micrometer-sized water droplet illuminated by a short laser pulse (duration, 0.4 µs). First we find electromagnetic surface forces, assuming that the surface is at rest; thereafter we find the distortion by using the linearized Navier–Stokes equation. We illustrate the motion as a function of time, up to 22 µs after passage of the pulse. This study generalizes the earlier one of Lai [J. Opt. Soc. Am. B6, 2430 (1989)] to the case of linear polarization and is in reasonable agreement with the experiment of Zhang Chang [Opt. Lett.13, 916 (1988)].
