MOPOS40 Simulation Investigation of the Detuning Curve
Xiaojian Shu, Yuhuan Dou, Yuanzhang Wang (IAP, Beijing)

The detuning curves of free-electron laser oscillators are calculated with the help of our three-dimensional code, which are compared with those from one-dimensional simulations and supermode theory, and the experiments. The influence of the optical guiding and other three-dimensional effects on the detuning curve is studied. It is found that the length of the detuning curve from three-dimemsional simulations is shorter than that from one-dimensional simulations and supermode theroy.
