Tóm tắt

We investigate the propagation dynamics of a pair of probe andcoupling laser pulses in a three-level type-V atomic medium under the condition ofelectromagnetically induced transparency (EIT) by numerical solving the MaxwellBloch equations for atoms and fields. Influences of the intensity and pulse area of thecoupling laser on the EIT formation of probe laser pulse are studied in a wide regionfrom micro- to pico-second of pulse duration. It is found that a nearly solition pulsecan be established at the smallest pulse area in the pico-second region and with thelargest pulse area in the micro-second region. These results can be important forapplications in all-optical switching, and quantum information processing andtransmission.
