Phenomena relevant to fragmentation of gallbladder stone during a pulsed laser action
were studied. Real conditions have been simulated. A stone was immersed in distilled water
and laser energy was delivered to its surface by an optical fiber. Two different cases
were studied: when the tip of the fiber was in contact with the stone and when it was at a
distance from it. Using ultra-fast shadowgraphy and interferometry, mechanism of
destruction of a stone due to laser-based lithotripsy was studied.
