Abstract

See full text

A method for generating output laser pulses from input laser pulses includes causing the input laser pulses to temporally successively pass through an optical component with temperature-dependent power efficiency. The optical component is heated by the passing of the input laser pulses. The input laser pulses emerge from the optical component as output laser pulses. The method further includes calculating a current temperature or a current temperature difference of the optical component, or a temperature-dependent current parameter based on all preceding input laser pulses or output laser pulses that have contributed to the heating of the optical component, and setting a power of a current input laser pulse based on the calculated current temperature, or the calculated current temperature difference, or the calculated current parameter, so that an associated output laser pulse has a pulse energy that deviates from a predefined pulse energy by less than 5%.
