Researchers Submit Patent Application, "Short Pulse Laser System, And Method For Generating Laser Pulses", for Approval (USPTO 20230335964).

"A known problem is that the pulse quality of the non-linearly compressed laser pulses is not perfect and a certain amount of the pulse energy is in secondary pulses or a temporal background of the laser radiation. "The present disclosure also relates to a method for generating laser pulses, in which pulsed laser radiation consisting of a temporal sequence of laser pulses is generated and the generated laser pulses are spectrally broadened in a non-linear manner by applying a chirp, wherein a group delay dispersion variable along the beam path is applied on the laser pulses, which group delay dispersion effects an at least partial compensation of the chirp.
