A repetitively pumped ruby laser including long (16 m) intracavity optical delay line is described emitting microsecond pulses. A prototype model of laser lithotriptor was made using this laser, and histological and clinical studies were made.© (199

The model of human calculi fragmentation process by laser radiation is proposed. It is shown, that under the conditions typical for laser lithotripsy, plasma can not be considered as the effective transformer oflaser radiation energy intoshock waves.

Physical mechanisms of ms laser lithotripsy in the visible range are discussed. Theoretical model for the case of stones which can be represented as a high-scattering low-absorption medium containing high-absorptive organic micropores is developed. T

Theoretical model of microsecond shockwave laser lithotripsy is developed. The destroying stone is considered to be a medium with low absorption and high scattering which contains high-absorptive organic inclusions. Laser radiation penetrates deep in
