摘要:
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.
