An expression for point spread function has been obtained for a four-wave converter in resonant medium modelled by four-level energy scheme. The dependences of point spread function width from pumping wave intensity and resonant medium parameters have been found.
Keywords: points spread function, four-wave converter, resonant nonlinearity.
