Abstract
The gain of an electromagnetic wave in a free electron laser is calculated. It is demonstrated that when the electron beam develops instabilities, this gain can be enhanced. Calculations for the case of the two-stream instability show that the growth rate is more than seven times larger and the gain per pass can be increased by more than two orders of magnitudes.
