Aa. Borshch et al., NEW MATHEMATICAL-MODEL OF TRANSIENT 2-BEAM ENERGY-EXCHANGE DURING RECORDING OF DYNAMIC TRANSMISSION HOLOGRAMS, Quantum electronics, 27(11), 1997, pp. 998-1000
A proposal is made and a justification is given of a new mathematical
model of transient energy exchange between two concurrent waves in med
ia with a local noninstantaneous nonlinear response. The relaxation ti
me of this response is taken into account.
