| Abstract: | The coefficient of selective reflection at oblique incidence from two-level
atoms confined between two dielectric walls is calculated in this paper.
It is found to
be related to the transient behaviour of atoms after colliding with the wall
and the distribution of the field inside the vapour corresponds to L /
\lambda , with L the thickness of the film and \lambda the incident
wavelength. We find that the sub-Doppler structure is manifest both for
normal incidence and small angle oblique incidence. It is feasible to detect
the real part of selective reflection in several cases that have not been
achieved before. |
