We have generated x-ray radiation from the nonlinear Thomson scattering of a [Formula presented] laser beam on plasma electrons. A collimated x-ray radiation with a broad continuous spectrum peaked at 0.15 keV with a significant tail up to 2 keV has been observed. These characteristics are found to depend strongly on the laser strength parameter [Formula presented]. This radiative process is dominant for [Formula presented] greater than unity at which point the relativistic scattering of the laser light originates from MeV energy electrons inside the plasma.
