Abstract :
To decrease power loading on cavity mirrors, a Gaussian mode with a very short Rayleigh length could be employed. We study the physics of the FEL interaction while shortening the Rayleigh length in the FEL oscillator. The results can be applied to the Industrial Laser Consortiumʹs UV FEL and to high average power FELs in general.
