    "abstract": "Stimulated Raman backscattering (RBS) of intense laser radiation confined by\na single-mode plasma channel with a radial variation of plasma frequency\ngreater than a homogeneous-plasma RBS bandwidth is characterized by a strong\ntransverse localization of resonantly-driven electron plasma waves (EPW). The\nEPW localization reduces the peak growth rate of RBS and increases the\namplification bandwidth. The continuum of non-bound modes of backscattered\nradiation shrinks the transverse field profile in a channel and increases the\nRBS growth rate. Solution of the initial-value problem shows that an\nelectromagnetic pulse amplified by the RBS in the single-mode deep plasma\nchannel has a group velocity higher than in the case of homogeneous-plasma\nRaman amplification. Implications to the design of an RBS pulse compressor in a\nplasma channel are discussed.",
