TI - Four-Dimensional Models of FEL Amplifiers and Oscillators J2 - Proc. of FEL2015 AB - New four-dimensional models of free electron lasers (FELs) are described, for both amplifier and oscillator configurations. Model validation and benchmarking results are shown, including comparisons to theoretical formulas and experiments.
