Cj. Mckinstrie et al., SIDEWARD STIMULATED RAMAN-SCATTERING OF A SHORT LASER-PULSE IN A PLASMA CHANNEL, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(1), 1997, pp. 1032-1036
The evolution of sideward stimulated Raman scattering (SRS), in time a
nd two spatial dimensions, is studied analytically for boundary condit
ions representative of a laser pulse propagating in a plasma channel.
The partial reflection of Stokes light by the channel walls allows a s
patial eigenmode to form in the body of the pulse. After this eigenmod
e has formed, it grows exponentially in time for the subsequent durati
on of the pulse. Even weak reflections enhance the growth of sideward
SRS significantly.
