Kinetic equations describing the behavior of an atom in nonresonant classic
al and broadband squeezed fields are obtained. The two-pulse photon echo un
der the conditions of additional illumination by nonresonant fields is stud
ied theoretically. It is shown that investigation of the photon echo decay
allows one to determine the main parameters of the squeezed field. (C) 2001
