摘要：The spatial and temporal structure of an object wave has been analyzed for a four-wave radiation converter in a transparent two-component medium with regard for the electrostriction and Dufour effect. The bandwidth of high-efficiency conversion has been shown to increase over time. We have shown that for a steady-state spatial spectrum of object waves, the spectrum maximum shifts toward lower spatial frequencies, whereas the bandwidth of high-efficiency conversion is decreasing as the ratio of wavenumbers of pumping waves gets increasingly deviated from unity.
