The production of ultrashort (fs) x-ray pulses through Thomson scattering of high power laser pulses off relativistic electron bunches generated by laser-plasma accelerators is discussed. These accelerators can typically produce two types of electron bunches: i) a high charge bunch with a broad energy distribution, resulting in x-ray pulses with high flux and a broadband spectrum, and ii) electron bunches with a narrow energy distribution, resulting in an ultrashort x-ray pulse with a nearly monochromatic spectrum. Nonlinear Thomson scattering (high laser intensity) will be considered, as well as the effects of the laser pulse profile. Thomson scattering may provide a useful diagnostic for determining the electron bunch properties via the scattering x-ray spectrum.
