Free electron lasers with short Rayleigh length
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 Consortium's UV FEL and to high average power FELs in general.
