Abstract :
The amplification of radiation is calculated in the beam frame for a free electron laser (FEL) with a planar or helical undulator. The effect of the radiation force upon the transverse electron trajectory is included; this effect accounts for one-half of the gain in the undulator regime. Our calculated gain agrees with conventional formulas.
