Abstract
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.
