Abstract

To generate radiation with high spatial - and temporal quality in free-electron lasers (FELs), oscillators are to be used which are based on the combination of low gain with a large number of roundtrips in a low-loss optical resonator. Clearly, in this situation any additional loss or aberration may seriously degrade the performance and beam quality, and this becomes extremely important for high average power FEL oscillators. Nevertheless, so far no systematic study has been made how various mirror aberrations affect the performance of such low gain FEL oscillators. Here we present the first results of such a study. The approach is based on the optical propagation code OPC with GENESIS 1.3 and MEDUSA as gain codes.
