    摘要： A device for spectrally broadening a laser pulse is disclosed. The device includes a multipass arrangement having a convex mirror and a concave mirror, the convex mirror and the concave mirror being arranged relative to each other such that a laser pulse coupled into the multipass arrangement is reflected at least once from the concave mirror to the convex mirror and at least once from the convex mirror to the concave mirror. Further, the device includes a nonlinear optical medium arranged at least partially within the multipass arrangement such that the laser pulse coupled into the multipass arrangement passes through the nonlinear optical medium multiple times. The disclosure also relates to a laser system having a device according to the disclosure for spectral broadening of a laser pulse.
