Proposed generation of subfemtosecond VUV pulses from high-order harmonics

Publication Date



We propose a method for producing sub-femtosecond VUV pulses by compressing the high order harmonic radiation emitted from a nonlinear medium driven by an intense, ultrafast laser pulse. We present single atom calculations of the harmonic amplitudes and phases as well as simulations of a VUV compressor. Single harmonics from a 27 fs driving pulse can be compressed to less than 2 fs duration, and several adjacent harmonics with similar phase structure can be combined within the same compressor to produce an attosecond pulse.
