【Abstract】 Gain properties of free-electron lasers are calculated in which a gradient magnetie field is superposed on a spacially periodic magnetic field along the axis of the wiggler. It is shown that better operating properties of laser gain are obtained by the use of gradient magnetic field than of uniform magnetic field.更多还原
