Pulsed laser ablation of blood clots in a fluid-filled blood vessel is always accompanied by an explosive evaporation process. The resulting vapor bubble rapidly expands and collapses to disrupt the thrombus (blood clot). Thus, the laser-induced bubble formation plays an important role in the thrombus removal process. In this study the effects of fiber size, material, and boundaries on laser-induced cavitation bubbles have been investigated through visualizing of the cavitation phenomena that take place in liquids and on soft target with a microsecond strobe or high speed framing camera.
