The new method to create Single Bubble Sonoluminescence

Abstract

Sonoluminescence is a phenomenon which is known for some time, relatively easy to produce but still not fully understood. A milestone was discovery of procedure for creating Single Bubble Sonoluminescene (SBSL) \cite{gaitan} in 1989. Sonoluminescence in single bubble at well defined conditions, periodically produced for a long time, is well suited for a systematic study. This procedure for SBSL was for many years considered as standard one for a study this interesting phenomenon. About single bubble sonoluminescence was published wealth of sometime very surprising results, however generally accepted solution to the problem is still missing. Another way (technique based on water hammer) to produce sonoluminescence was published in 2003 \cite{waterham}. By this method many orders of magnitude stronger signal in comparison with standard procedure can be produced and also new phenomena have been observed. In this paper we describe another method to produce relatively stable SBSL. New technique is closely related to standard one. But it for example does not need degassing of working liquid and there is one more handle for a study of the sonoluminescence.
