چکیده
The particle optics code GPT [1] has been applied to study the single pass electron beam interaction with an external laser field in the undulator system of a free electron laser. In particular, this code has been used to simulate the laser electron beam interaction in an optical klystron. Micro-bunching as a result of the interaction of the electron bunch with an electromagnetic pulse is presented. The energy exchange during the interaction calculated with GPT gives the gain curve of the optical klystron.
