We present a theoretical model of a free electron laser (FEL) in the high gain Compton regime with a variable wiggler patterned after the work of Bonifacio, Pellegrini, and Narducci for the constant wiggler configuration. This model incorporates a variable wiggler subject to the constraint {lambda}{sub {ital w}B{ital w}} = constant where {lambda}{sub {ital w}B{ital w}} are the spatial periodicity and field strength of the wiggler, respections of motion are numerically integrated for various spatial dependencies of the wiggler wavelength. The subsequent behavior of the radiation field relative to position and wiggler geometry is then presented, demonstrating significant improvement over the constant wiggler configuration.
