Amplification of Stimulated Raman Scattering in the 22005300-cm1 Stokes Region by F_2~+ Color Centers in a LiF Crystal

摘要

A method for lowering the threshold of excitation and simultaneous amplification of stimulated Raman scattering (SRS) intensity with the help of a lasing broadband medium is proposed. In this case, an optically coupled system appears. Various types of vibrations are excited and phased by a broadband medium in an SRS converter owing to pumping and lasing radiation, including composite vibrations falling within the amplification band of this medium.
