Driving Pulse

We study theoretically the high-order harmonic generation from neon atoms in a two-color laser field, which is synthesized by a 5-fs/800-nm fundamental driving pulse and a 12-fs/1600-nm subharmonic controlling pulse. Numerical simulations show that the harmonic emission is strongly sensitive to the carrier-envelope phase (CEP) of either the fundamental driving pulse or the subharmonic controlling pulse. When neon atoms are driven by such laser pulses with optimal CEP, the generated high-order harmonic spectrum is a supercontinuum that corresponds to single attosecond pulse. The calculation results are explained in terms of the semiclassical "recollison" model and the time-frequency analysis.
