Abstract: | We study a novel method to produce extremely short pulses of radiation in a resonant medium via induced transparency by means
of adiabatic periodic modulation of atomic transition frequencies by far-off-resonant laser field, which causes linear Stark
splitting of atomic energy levels resulting in partial transparency of an optically deep medium and drastic spectral modification
of an incident resonant radiation. We find the regimes where the output spectrum corresponds to extremely short pulses and
discuss several possible experimental realizations of generation of attosecond pulses in Li2+ ions and femtosecond pulses in atomic hydrogen with commercially available facilities. |
