Аннотация: Spatial effects in inversionless amplification and generation of two coupled waves in a two-level medium in the presence of resonant pumping radiation are studied. Criteria for the fulfillment of the approximation of optically thin media are found. The inclusion of propagation effects is shown to lead to the possibility of inversioПоказать полностьюnless amplification near the line center where amplification is absent in optically thin media.
