### Abstract

A noniterative phase retrieval method for coherent anti-Stokes Raman scattering spectrum analysis is presented. This method facilitates the computation of the real and imaginary parts of the effective third-order susceptibility X when only its modulus is known. One obtains this result by approximating the squared modulus |X|^{2} by the maximum entropy model and using some *a priori* information on X.
