At low energies a single spherical shock wave and cavitation bubble is generated from laser beam waist, and shock wave radius tends to saturation with energy increasing. At higher energies long laser filament in water is fired, that leads to the cylindrical shock wave generation and cavitation bubble in every nonlinear focus. The diameter of cavitation bubble depends on the distance from the first nonlinear focus.
