The invention relates to a Laser system for hard body tissue ablation, comprising a pumped laser, wherein the laser system is adapted to be operated in pulsed operation with several individual pulses (1) of a temporally limited pulse length (tp) and wherein the individual pulses (1) follow one another with a temporal pulse spacing (Ts). The pumped laser has a inversion population remaining time (tR), the inversion population remaining time (tR) being the time within which in the absence of pumping the remaining inversion population of the laser energy status is reduced by 90%. The pulse spacing (Ts) is in the range of ≥ 50 µs and ≤ to the inversion population remaining time (tR).
