Abstract

The spectroscopic behaviour of atomic systems where the reservoir of spontaneous emission modes is in a squeezed vacuum state has been extensively studied recently following the original paper of Gardiner [1], This work has been stimulated by the advent of squeezed light sources such as parametric amplifiers, though as yet actual experiments are rare [2], Theoretical studies of modifications to spontaneous emission, transition frequency shifts, resonance fluorescence spectra and statistics, probe absorption spectra, optical double resonance effects, coherent population trapping, laser cooling, optical bistability and multi-wave mixing due to the squeezed vacuum have been made. The atomic systems treated include two level and multi level cases. Much of this work is reviewed by Parking [3].
