Optical precursors in transparent media

open access: yes, 2009
We theoretically study the linear propagation of a stepwise pulse through a dilute dispersive medium when the frequency of the optical carrier coincides with the center of a natural or electromagnetically induced transparency window of the medium (slow ...

Modifying the lifetime of an unstable system by an intense electromagnetic field [PDF]

open access: yes, 1999
We study the temporal behavior of a three-level system (such as an atom or a molecule), initially prepared in an excited state, bathed in a laser field tuned at the transition frequency of the other level. We analyze the dependence of the lifetime of the
