摘要
Observations of periodic intensity bursts from a free electron laser oscillator operating in the microwave regime are reported. Their periodic separation (approximately 40 ns) equals the radiation round-trip time, and their width is approximately the slippage time (approximately 5 ns). Unlike previous studies, the bursts occur in the small-signal regime, near the oscillation threshold. The observations are compared with theoretical results from an impulse response model of the free electron laser.
