Abstract
A method of removing microvessels includes applying a burst of acoustic energy at a target location, applying a pulse of optical energy at the target location, and promoting cavitation at the target location by synchronizing an arrival of the burst of acoustic energy and the optical energy at the target location. The burst of acoustic energy has a pressure below 5.0 MPa. The pulse of optical energy at the target location has a fluence less than 100 mJ/cm2. At least a portion of the pulse is concurrent with the burst and the optical energy has an optical area that is overlapping with an acoustic area of the acoustic energy at the target location.
