Abstract
In a free-electron laser oscillator operating with short electron bunc hes, the desynchronism between electron bunches and optical pulses res ulting in the shortest buildup time to saturation is different from th at giving the largest saturated power. In this Rapid Communication we present an experimental demonstration of the dynamic variation of the cavity desynchronism. This is achieved by ramping the electron-bunch r epetition frequency during part of each 12-mus machine pulse. A high s mall-signal gain and a high saturated power are obtained simultaneousl y.
