Abstract
An optical pulse compressor having a single deflecting dispersive optical element in the form of a diffraction grating (10) or prism for temporal compression of an optical pulse, the frequency of which increases during the pulse duration. An elongated target (T) for receiving the compressed pulse is arranged in parallel with an output surface of the grating or prism. To increase the inclination of the pulse front for effective synchronous travelling wave excitation of the target the output surface of the diffraction grating or prism can be interfaced by an immersion medium or the beam path can be made to converge in the plane containing the target by a cylindrical lens or a reducing imaging optical system can be arranged between the grating or prism and the target.
