Laser pulse propagation in a medium optically dressed by a phase-modulated field

Year: 2016

Type: article

Abstract: Pulse propagation is studied in an atomic medium in the Λ configuration with the control field having a periodically varying phase (chirp). Numerical calculations of a probe-pulse shape have been performed and the results are compared with those for an approximate model neglecting absorption and nonadiabatic effects. It is shown that transparency occurs for probe pulses having a sufficiently narrow envelope and an appropriately suited chirp. For other chirped probe pulses the evolution of their spectra along a sample is studied. Using a projection method, one can divide a pulse into two components: one for which the medium is transparent and the remaining one for which it is opaque.
