Abstract

The influence of a continuous sound field on the first oscillation cycle and on the cavitation luminescence of a transient laser-induced bubble is investigated experimentally. The variation of the collapse phase is predicted with a simple numerical model and compared with experiment. Bubble dynamics is mainly influenced by three parameters: the phase of bubble generation, the size of the bubble, and the amplitude of the sound field. The experimentally found enhancement and reduction of the luminescence is discussed and several suggestions are made for further boosting of the collapse strength.
