HIGH EFFICIENCY MONOCHROMATIC X-RAY SOURCE USING AN OPTICAL UNDULATOR
摘要
A method of generating energetic electromagnetic radiation comprises, during each of a plurality of separated radiation intervals, injecting laser radiation of a given wavelength into an optical cavity that is characterized by a round-trip transit time (RTTT) for radiation of that given wavelength. At least some radiation intervals are defined by one or more optical macropulses, at least one optical macropulse gives rise to an associated circulating optical micropulse that is coherently reinforced by subsequent optical micropulses in the optical macropulse and the electric field amplitude of the circulating optical micropulse at any given position in the cavity reaches a maximum value during the radiation interval.
