Measurement of the transverse mode excitation in the stimulated emission of the ACO free electron laser
Abstract
Measurements of the off-diagonal terms in the transverse gain matrix of the free electron laser were obtained and analyzed under this contract. Quantitative agreement was demonstrated with the low-diffraction theory. The scaling was demonstrated as a function of analysis distance, electron beam size, and resonance parameter. The effects of multiple mode input were observed, and a general analytic expression derived for this regime.
