Inversionless amplification and laser-induced transparency at the discrete transitions and the transitions to continuum

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/88896The effects of coherence of quantum transitions and the interference of resonant nonlinear optical processes on the spectra of absorption, amplification, and nonlinear-optical generation are considered. The most favorable conditions are discussed for the inversionless amplification, resonant refraction in the absence of absorption and for resonant enhancement of nonlinear-optical generation at the discrete transitions and the transitions to continuum.Latex, 19 pages, 12 eps figures, invited review paperQuantum PhysicsOpticsInversionless amplification and laser-induced transparency at the discrete transitions and the transitions to continuumtext
