Pulse propagation in an autoionization medium with double Fano profile

摘要: We discuss the propagation of a short laser pulse in an auto- ionizing (AI) medium with degenerate double Fano model. By solving numerically coupled equations for atoms and fields we show that by proper choice parameters involved problem (contrary to case considered (E. Paspalakis, N. J. Kylstra, P. L. Knight, Phys. Rev. A60 (1999)) have now two asymmetry parameters) one can eliminate almost completely absorption propagation. It means transparency medium. From connection between population trapping pulsed field which has been fixed Paspalakis et al., (1999) conclude this leads presence (or existence “dark” states) atomic system. Moreover, instead value detuning dark states exist AI level, find such values levels.
