We model the process of ultra broadband light generation in which a pair oflaser pulses separated by the Raman frequency drive a Raman transition. Incontrast to the usual approach using separate field envelopes for the differentfrequency components, we treat the field as a single entity. This requires theinclusion of few-cycle corrections to the pulse propagation. Our single-fieldmodel makes fewer approximations and is mathematically (and hencecomputationally) simpler, although it does require greater computationalresources to implement. The single-field theory reduces to the traditionalmulti-field one using appropriate approximations.Comment: 6 pages, two 3-part figure
