Four-Wave Interaction on Resonance and Thermal Nonlinearities in a Scheme with Concurrent Pump Waves at High Conversion Coefficients
We have obtained the dependencies of the conversion coefficient and the bandwidth of spatial frequencies on the intensity of pumping waves for a four-wave converter of radiation at the resonance and thermal nonlinearity in a scheme with concurrent pumping waves. The connection between the conversion coefficient and spatial selectivity of the four-wave radiation converter has been found.
