- Аннотация: Using shadow photography we observed the evolution of multiple cavitation bubbles, excited by a femtosecond laser pulse in water, up to the microsecond time scale. In the tight focusing geometry a single filament is formed. The filament becomes the center of the cavitation region formation. When aberrations were added to the optical scheme, aberration hot spots along the filament axis are formed. At high energies (more than 40 μJ) the filaments in the aberration hot spots are fired. Thereby a complex pattern of the cavitation bubbles is created. The bubbles can be isolated from each other or can form an exotic 'drop-shaped' cavitation region, whose evolution at the end of its 'life', before the final collapse, contains the jet emission. The dynamics of the cavitation pattern were investigated from the pulse energy and the focusing. An increase of the numerical aperture of the focusing optics leads to an increase of the cavitation area length. A strong interaction between the bubbles was also found. This leads to a significant change in the bubbles' evolution, which is not yet in accordance with the Rayleigh model.
