چکیده
We investigate theoretically the phenomenon of so-called fast light in an unconventional regime, using pulses sufficiently short that relaxation effects in a gain medium can be ignored completely. We show that previously recognized instabilities associated with coherent propagation in a gain medium can be tolerated in reaching the fast light goal of a pulse peak advance of one full peak width.

We investigate theoretically the phenomenon of so-called fast light in an unconventional regime, using pulses sufficiently short that relaxation effects in a gain medium can be ignored completely. We show that previously recognized gain instabilities, including superfluorescence, can be tolerated in achieving a pulse peak advance of one full peak width.

The admissibility condition of a mother wavelet is explored in the context of quantum optics theory. By virtue of Dirac’s representation theory and the coherent state’ property we derive a general formula for finding Mexican hat wavelets.

An approach featuring s-parametrized quasiprobability distribution functions is developed for situations where a circular topology is observed. For such an approach, a suitable set of angle-angular momentum coherent states must be constructed in appropriate fashion. PACS numbers: 03.65.Ca, 03.65.Fd
