1. A cleaning system configured for cleaning cavities filled with a liquid, the cleaning system comprising:
an electromagnetic radiation system comprising a radiation source for generating a radiation beam and an optical delivery system for delivering the radiation beam, wherein the delivery system includes a treatment handpiece and an exit component, wherein the treatment handpiece and the exit component are configured to irradiate the liquid within the cavity with the radiation beam, wherein a wavelength of the radiation beam is chosen for significant absorption of the radiation beam in the liquid, wherein the electromagnetic radiation system is adapted to be operated in pulsed operation with at least one pulse set containing at least two individual pulses, wherein a first pulse of the pulses is followed by a second pulse of the pulses with a pulse repetition time,
wherein the electromagnetic radiation system is adapted to generate a first vapor bubble within the liquid by delivery of the corresponding first pulse such that the first vapor bubble oscillates in an expansion phase from a minimal volume to a maximal volume and in a subsequent contraction phase from a maximal volume to a minimal volume,
wherein the electromagnetic radiation system is adapted to generate a second vapor bubble within the liquid by delivery of the corresponding second pulse at a location different to the location where the first vapor bubble is present at the time of generating the second vapor bubble, and
wherein the pulse repetition time is configured such that an onset time of the second vapor bubble is within a first contraction phase of the first vapor bubble, when the first vapor bubble has contracted from its maximal volume to a size in a range from 0.7 to 0.1 of the maximal volume.
