Abstract
There has been tried many methods how to generate single cavitation bubble. The purpose of
these experiments is to observe the surface impact of collapsing cavitating bubbles. The most of method are
based on spark to induced superheat limit of liquid. Here we compare the one of these methods – laser
induced breakdown (LIB) with more correct mechanical way using ultrasound as generator. There is
described the setup for ultrasound cavitation effecting the sessile bubble as well as random generated and
moving bubble. We visualize the cavitation bubble using high speed camera of speed 180 kHz. There are
observed interface instabilities as the ultrasound response.
