Phenomenological modelling of the harmonic power in the 1.5 Å FEL radiation LCLS experiment for γ = 26600, σ∊ = 1 × 10−4, ∊x,y = 0.4 µm rad, λu = 3 cm, k = 3.5. Harmonics in the phenomenological model (solid lines): n = 1, red; n = 3, green. The shadowed area denotes the range of experimental values for the third harmonics, reported by Ratner et al. (2011). |
