Abstract:
Dynamics of spatial spectrum of the object wave has been analyzed for four-wave radiation converter in an optically transparent medium. It has been shown, that such four-wave radiation converter performs filtering of high spatial frequencies. Over time the spatial frequency bandwidth cut out by four-wave radiation converter decreases leaving the steady-state value.

Key words:
four-wave radiation converter, wavefront reversal.
