Abstract

The invention relates to a stabilization method and device for a passively Q-switched laser, which is pumped by at least one pump laser source (6, 6'; 12). The pump power of the pump laser source (6, 6'; 12) is modulated between a pump level lower than and a pump level above the lasing threshold for the Q-switched laser at frequencies which are always lower than a self-pulsation frequency of the Q-switched laser.
