Abstract
Method and systems are disclosed for generating amplified output laser pulses with individually predefined pulse energies at individually predefined times at an output by providing a pulse sequence of input laser pulses having the same pulse energy and the same temporal pulse interval smaller than the temporal pulse interval between two adjacent output laser pulses, selecting the input laser pulses that arrive at the output at or about the predefined times, amplifying the selected input laser pulses with an optical amplifier, wherein at least one sacrificial laser pulse is inserted into the pulse sequence of the selected input laser pulses before the subsequent one of the two successive input laser pulses to be amplified, and reducing the pulse energies of the amplified input laser pulses to predefined pulse energies by time-controlled partial decoupling depending on their pulse intervals from the corresponding immediately preceding amplified input or sacrificial laser pulse.
