ONE-DIMENSIONAL INTENSE LASER-PULSE SOLITONS IN A PLASMA

A general analytical framework is developed for the nonlinear dispersi on relations of a class of large amplitude one-dimensional isolated en velope solitons for modulated light pulse coupled to electron plasma w aves, previously investigated numerically [Kozlov ed al., Zh. Eksp. Te or. Fiz. 76, 148 (1979); Kaw et al., Phys. Rev. Lett. 68, 3172 (1992)] . The analytical treatment of weakly nonlinear solitons [Kuehl and Zha ng, Phys. Rev. E 48, 1316 (1993)] is extended to the strongly nonlinea r limit. (C) 1997 American Institute of Physics.
