Abstract. We derive the main equations that describe the evolution of the spectral properties for two different nonlinear optical processes: second harmonic (SH) generation as representative of the quadratic processes and cross polarized wave (XPW) generation as representative of third order nonlinear optical processes. The role of both second order and third order spectral phases on the output parameters of the SH wave and the XPW are studied. The approach can be applied to other nonlinear optical processes as well.
