FIELD: medical equipment.
SUBSTANCE: methods and devices for lithotripsy using a pulsed laser are proposed to ensure a high ablation rate while minimizing retropulsion of ablation products.
EFFECT: method and a laser system for treating calculi in a human or animal body comprising a laser emitting a sequence of laser pulses, the laser being capable of operating in an amplitude modulation mode, in which the emitted laser pulses are characterized by the following parameters: a constant pulse repetition rate and a periodically changing peak power or pulse energy or peak power or pulse energy with amplitude modulation period Na equal to the number of pulses in the amplitude-periodic group of pulses.
