Abstract

Several high power free-electron lasers (FELs) are currently under design, operational or being upgraded. One central issue is the beam outcoupling and mirror deformation due to absorbed power. Here we present an extension to the OPC code that allows it to model mirror distorions. We use this code to model the high average power vacuum ultra violet FEL oscillator of the 4th generation light source. Both Genesis 1.3 and Medusa are used to calculate the gain provided by the undulator. Our findings indicate that the high gain oscillator is quite resilient to thermal mirror deformation and operation well into the kW range of average power can be expected.
