Dependence of the measured ratio Ra on the FEL gain ratio Gn/lc in the fundamental FEL oscillation (open circle) and the third-harmonic FEL oscillation (solid circle). The solid and dotted lines are the average values for the fundamental FEL oscillation and the third-harmonic FEL oscillation, respectively, in the region Gn/lc > 1.1. |
