We have formulated and obtained analytical expressions for Thomson bac
kscattered X-ray radiation for an electron beam incident on a linearly
polarized electromagnetic undulator at a small angle. The analytical
expressions are valid for fundamental and harmonics with arbitrarily l
arge laser intensities. The intensity distribution pattern is evaluate
d numerically.
