(a) Variation of the profile of three-color FEL pulses with the undulator field parameter on the axis in the normal planar radiator, in which solid lines represent K0 = 1.06, dashed lines represent K0 = 1.03 and dotted lines represent K0 = 0.99. (b) Variation of the three-color FEL power with the offset of the vertical bunch orbit in a normal planar radiator, in which Δy is the deviation from the orbit of y = 0 mm at the head of the bunch. Green crosses represent 60 nm, blue circles represent 48 nm and red squares represent 40 nm. |
