Abstract
A three dimensional simulation software system developed to estimate a free electron laser (FEL) gain has been applied to FEL using a standa rd plane polarized wiggler and an alternately shifted magnet wiggler. It is seen for the latter wiggler that a large filling factor could be selected and each maximum gain corresponding to each orbit of electro n beam concentrates at a certain frequency region of FEL radiation. It is, therefore, implied that a proper shift between the adjacent magne ts in the wiggler produces the improvement of the FEL gain.
