Abstract
The degenerate and counterpropagating waves of the degenerate four-wave mixing process will appear nondegenerate and noncounterpropagating to a moving observer. A Lorentz-transformed degenerate four-wave mixing is seen to be indistinguishable from coherent anti-Stokes Raman scattering. Inverse transformations which render any given coherent anti-Stokes Raman scattering the appearance of a degenerate four-wave mixing are also presented.
