View the Complete Application at the US Patent & Trademark Office
An apparatus and method are provided for producing x-rays by generating high harmonic radiation with long wavelength light. The use of long wavelength light increases the acceleration time of the electrons in the light field. Keeping the atomic species and light intensity unchanged, the x-ray photon energy increases by a factor of two to four when the fundamental wavelength increases by a factor of two.
