ABSTRACT:
A device for generating short laser pulses comprises a laser oscillator for generating a first laser pulse, a pulse compression element which retroreflects the first laser pulse by stimulated Brillouin scattering (SBS) as a temporally shortened pulse, a reflection element into which the temporally shortened laser pulse is retroreflected for further temporal shortening of the pulse, and an outcoupling element disposed between the pulse compression element and the reflection element for outcoupling the so shortened laser pulse.
