抄録

The dynamics of high-speed phenomena induced by focusing of pulsed laser beam in liquid nitrogen is studied experimentally. Before the growth of a spherical bubble, a series of nonspherical phenomena is observed. The laser-induced breakdown creates luminous plasma around the point of focus. When the pulsed laser beam is switched off, the relaxing plasma and the resulting gas form a nonspherical bubble, which emits a nonspherical shock wave. Then several compression waves following the preceding shock wave are emitted from the bubble. As they overtake the shock wave, they make both the shock wave and the bubble spherical. A possible mechanism for these phenomena is considered.
