Simulations of shock waves and cavitation bubbles produced in water by picosecond and nanosecond laser pulses

PDF Version Also Available for Download.

Description

The authors compare numerical simulations of bubble dynamics in water with experiments performed at the Medizinisches Laserzentrum Luebeck. Spatial and temporal features of the laser beam were modeled. Plasma growth was predicted using a moving breakdown model. The authors compare the measured and calculated positions of the shock front and the bubble wall as a function of time after optical breakdown in water. Nd:YAG laser pulses of 30-ps 1-mJ and 6-ns 10-mJ were simulated. The authors have extended previous work in which picosecond deposition was modeled as temporally instantaneous and spatially uniform.
