Coherent effects in the propagation of ultrashort light pulses in resonant media. Part II (Review)
I A Poluéktov, Yurii M Popov, V S Roĭtberg
This part of the review deals with coherent effects in the interaction of ultrashort light pulses with media characterized by degenerate transitions, including semiconducting media (in the direct band-band transition region), and with media exhibiting two-photon resonances. It is shown that the self-induced transparency can appear under such conditions and the properties of this effect are studied. A review is made of experimental investigations of the coherent bleaching of various media. The paper ends with a list of the most urgent problems requiring clarification.
