摘要：

Bubble behavior and the radiation mechanism from a laser-induced collapsing bubble were investigated theoretically using the Keller-Miksis equation for the bubble wall motion and analytical solutions for the vapor inside the bubble. The calculated time-dependent bubble radius is in good agreement with observed ones. Also, the calculated half width and the total emission of the luminescence pulse from the vapor bubble at the collapse point agreed well with the observed value of 8 nanoseconds and 2.3 mW, respectively. The inert gas content inside the laser-induced vapor bubble was too small to produce light emission due to bremsstrahlung.
