Chirped pulse amplification in an extreme-ultraviolet free-electron

WebChirped-pulse amplifiers are seeded with low-energy ultrashort pulses temporally broadened in a dispersive pulse stretcher to permit for amplification without damaging the gain medium. The chirp of the amplified pulses is subsequently removed in a pulse compressor introducing a group-delay dispersion (GDD) of opposite sign. The pulse WebThe pulse duration of the chirped pulse can be made up to 100 thousand times longer than the original pulse and its intensity is reduced accordingly.
