Nonlinear optical effects

Characteristics of stimulated thermal scattering in a bounded region of moving medium

A. V. Berdyshev, A. P. Napartovich


Abstract: An analysis is made of the growth of an instability of a high-power electromagnetic wave in a bounded region of a moving medium with a thermal nonlinearity mechanism. A study is made of the one-dimensional case using the approximation of weak parametric wave coupling. The conditions for an absolute instability in this system are derived.
