The dynamic behavior of a free electron laser oscillation on an electron storage ring has been studied. We have measured time dependent micropulse evolution using a streak camera with a dual-sweep. Continuous lasing which appears under detuned condition has been ascertained to consist of discrete evolving groups of micropulses. In the gain-switching mode, bunch lengthening of the electrons due to bunch heating by the interaction with the laser was clearly observed.
