We present a plane wave analysis of near degenerate four-wave mixing in a Kerr medium within the Raman-Nath approximation. Our theory, which includes pump depletion, yields simple closed form solutions for the nonlinear reflection and transmission coefficients of arbitrary scattering order. The ...
Kapitsa-Dirac scattering problem is solved in Raman-Nath approximation without restrictions on the value of resonance detuning. Formula for the scattering amplitude is obtained in the form of a definite integral. It is shown that in case of Gauss-type superposition initial states the spectrum of ...

In this work we present a general formulation of the corrections to the Raman-Nath approximation for the diffracted field by a volume hologram, based on integral equations. An approximate analytic expression is given for the first correction. Numerical evaluations of this correction are also ...
The N-th order approximation (NOA) method is applied to the diffraction of light by ultrasound, in cases of oblique incidence of the light. A truncated system of Raman-Nath equations is integrated numerically by means of an eigenvalue method. The thus obtained theoretical curves for the light...
The number of photons in the modes were calculated in the Raman-Nath regime in the approximation of adiabatic following. It is shown that in the course of transitions an initially populated mode is generally not completely emptied, and the oscillating part of photons increases with the total ...
