Abstract : The discovery of a single bubble sonoluminescence has led to several interesting and remarkable observations. Among these are picosecond length light flashes and a level of synchronicity several orders of magnitude greater than the period of the applied acoustic field. Although new and unique observations concerning this phenomenon are being rapidly reported, an adequate explanation for the physical mechanisms that give rise to single bubble sonoluminescence has never been given. We describe here a few highlights of our recent research in our ongoing efforts to understand this complex phenomenon.
