Abstract
A multicomponent wiggler scheme is presented as a possible solution to the problems associated with start up and saturation of a tapered wiggler free-electron laser oscillator: low small-signal gain and large shift of the output radiation frequency with input power. Optimization of the scheme is analyzed and it is shown that appropriate wiggler configurations can be found that enhance by an order of magnitude the small-signal gain and eliminate the shift in radiation frequency with input power.Keywords
