METHODS AND DEVICES FOR SUPPRESSING NON-LINEAR DYNAMIC EFFECTS IN A LASER

摘要

The invention relates to methods for suppressing or preventing non-linear effects, such as bifurcations of the emitted intensity, in lasers. Also disclosed are laser arrays which are configured so as to be operated without allowing such effects to occur. In order to suppress non-linear effects in the laser emission, the parameters of the laser array are selected such that non-linear effects are prevented from occurring from the start and the laser emits in an inherently stable manner. Alternatively, operation of the laser is dynamically regulated by varying at least one adjustable variable that influences laser emission in accordance with at least one error signal which is based on the extracted pulse energy of the laser emission in such a way that an unstable behavior of the laser emission is prevented or suppressed.
