In a method for generating a series of laser pulses with a laser assembly, the laser assembly comprises at least two reflecting members, a laser medium and an electro-optical modulator. The method comprises the steps of: operating the laser assembly in a light amplifying mode, wherein an amplified laser pulse is provided; and running a pulse extraction sequence. According to the present invention, the pulse extraction sequence is run by applying a defined voltage change (40) with reference to the amplification voltage, wherein the changing of the voltage is adjusted such that at least one intermediate switching state is generated on the side of the electro-optical modulator by applying an intermediate voltage within a time period. The intermediate switching state provides a particular change of polarization of the amplified laser radiation by the electro-optical modulator, such that a final switching state is generated on the side of the electro-optical modulator by applying a final extraction voltage at the end of the time period, such that at least one intermediate interaction of the amplified laser pulse with the electro-optical modulator in the at least one intermediate switching state is provided as to at least one respective intermediate circulation of the amplified laser pulse, and such that a final interaction of the amplified laser pulse with the electro-optical modulator in the final switching state is provided as to a circulation of the amplified laser pulse successive to the at least one intermediate circulation. The present invention is designed to provide an improved laser system as well as a laser system enabling faster processing of material by optimized laser parameters, in particular by more efficient production of processing effects at the material. |
