Abstract
A device () for illuminating a sample () is described, having: at least one pulsed laser light source () for repeated emission of a first laser pulse along a first light path () and of a second laser pulse along a second light path () physically separated from the first light path; a superimposition element () for collinear superimposition of the two laser pulses in a shared light path (); a delay stage () arranged in the first or the second light path (), for delaying one of the two laser pulses relative to the other laser pulse in such a way that the two laser pulses sent along the shared light path () onto the sample () exhibit a temporal superimposition; a shared chirp unit () arranged in the shared light path (), for frequency-modifying influencing both of the first laser pulse and of the second laser pulse; and at least one separate chirp unit () arranged in the first light path (), for frequency-modifying influencing only of the first laser pulse. The shared chirp unit () and the separate chirp unit () are coordinated with one another in order to achieve a target state. The separate chirp unit () is coupled to a control system () by which the separate chirp unit () is controllable with a control parameter dependent on the wavelength of the first laser pulse in order to establish the target state.
