The discovery of self-focussing of intense laser beams 318 ) and the phenomena of self-induced transparency 318b) have stimulated a whole new class of experimental investigations which give information about the transient interaction between light and matter 318c)... 

Scenario associated with electromagnetically induced transparency (i.e., old levels, (levels 2,) and 22), and associated fields). Note that the inset shows excitation to two piratic states, as discussed in the text. Here our levels 2 0), ,), and EZ) are denoted, and 2), respectively. The laser wavelengths are denoted Xp and Xc.

Applications of control using moderate fields are discussed in Chapters 9 to 11. These fields allow for new physical phenomena in both bound state and continuum problems, including adiabatic population transfer in both regimes, electromagneti-cally induced transparency in bound systems, as well as additional unimolecular and bimolecular control scenarios.

In this paper we explore the design of microwave-based structures that can enhance the interaction of electromagnetic fields with cold-atom ensembles, leading to novel sensing modalities based on the quantum-mechanical behavior of these systems In particular, we discuss electromagnetically-induced transparency in a single uncondensed cold-atom cloud, and a two-cloud version of a SQUID, where the clouds are EEC s and take the place of the weakly coupled superconductors. 

Because it builds on the well-developed technology of atomic vapor filters, the phenomenon of electromagnetically induced transparency (BIT) is a promising...

The interest in quantum interference stems from the early 1970s when Agarwal [4] showed that the ordinary spontaneous decay of an excited degenerate V-type three-level atom can be modified due to interference between the two atomic transitions. The analysis of quantum interference has since been extended to other configurations of three- and multilevel atoms and many interesting effects have been predicted, which can be used to control optical properties of quantum systems, such as high-contrast resonances [5,6], electro-magnetically induced transparency [7], amplification without population inversion [8], and enhancement of the index of refraction without absorption [9]. 

It is expected within the framework of the theory of self-induced transparency that the pulse duration is either small or of the order of the relaxation time T2 in...
