Abstract

This paper describes preliminary experimental data of kidney stone fragmentation by the laser induced shock acoustic pulses. Acoustic pulses were produced in a thin layer of liquid as a result of absorption process of 1.06 micrometers radiation pulses. The phosphate Nd:glass laser operated in a pulse Q-switched regime with the pulse energy up to 10 J and pulse duration $OM 30 ns. The pressure induced by acoustic pulses on stones surface was reached up to 1-2 kbar in focal area, that was sufficient for stone destruction.
