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 χ when only its modulus is known. One obtains this result by approximating the squared modulus |χ|2 by the maximum entropy model and using some a priori information on χ.
