Abstract: We derive a nonlinear envelope equation to describe the propagation of broadband optical pulses in second-order nonlinear materials. The equation is first order in the propagation coordinate and is valid for arbitrarily wide pulse bandwidth. Our approach goes beyond the usual coupled wave description of chi((2)) phenomena and provides an accurate modeling of the evolution of ultra-broadband pulses also when the separation into different coupled frequency components is not possible or not profitable.
