ANALYSIS OF THREE FREQUENCY UNDULATOR INTENSITY AND GAIN DUE TO OFF AXIS CONTRIBUTION IN FREE ELECTRON LASER
Abhishek Verma , Vikesh Gupta
 
ABSTRACT
In this paper we study the three frequency undulator radiation and free electron laser gain for higher harmonics with the inclusion of off axis contribution. When electron enters the feld off axis it causes additional oscillations due to which intensity and gain reduction take place. To enhance the intensity and gain, we introduce a new scheme -the three frequency undulator scheme.
