Abstract

This paper describes the experimental investigation of the fragmentation processes of urinary stones by Cr,Nd:YSGG laser radiation (2.79 micrometers ). The laser operated in a pulse free-running regime with the pulse energy up to 1 J and pulse duration of 250-550 micrometers . It was shown that about 3 kJ of total radiation energy was required in order to ablate 1 g of urinary calculus. In those conditions, the stone substance was broken in a small fibrous-like dust. The maximum size of particles did not exceed 0.2-0.4 mm. The qualitative comparison of the stone ablation efficiency for the Cr,Er:YSGG laser, Cr,Nd:YSGG laser (1.06 micrometers ), and Cr,Tm,Ho:YSGG laser (2.09 micrometers ) was carried out.
