Research of the temporal spread of laser pulse by wake bubbles

Aiming at temporal spreading of laser pulse by bubbles,theoretic analysis and exploratory research were made for the light scattering properties and the multiple scattering effect of wake bubbles by Mie light scattering theory,and some signal waves of light back-scattering from bubbles at different distance were gained.The results indicate that wake bubbles influence the transmission of laser in water,which makes laser pulse spread in time evidently.
