A method of generating white light pulses () with a white light generation device () includes the steps of coupling pump laser pulses () into a white light generation crystal (), generating the white light pulses () by an optically non-linear conversion of the pump laser pulses () in the white light generation crystal () and detecting at least one pulse characteristic of at least one of the pump laser pulses () and the white light pulses (), wherein the white light generation device () is controlled using a control loop device () and the white light generation device () is adjusted in dependency on the at least one detected pulse characteristic. Furthermore, a white light generation device () for generating white light pulses () is described.

A laser pulse shaper device includes shaper unit including first dispersive element for spatially separating spectral components of laser pulses, second dispersive element for parallelizing and deflecting spectral components into Fourier plane of dispersive elements, and mirror for back-reflecting of laser pulses via dispersive elements, and light modulator in Fourier plane of dispersive elements, which is capable of modulating spectral components of laser pulses, wherein beam path of shaper unit includes forward beam path from first dispersive element via second dispersive element to mirror and return beam path from mirror via second dispersive element to first dispersive element, and focusing device is arranged at input side of forward beam path before first dispersive element for focusing spatially separated spectral components of laser pulses to Fourier plane of dispersive elements. Furthermore, a method for stretching or compressing laser pulses is described.
