Claim:
1. A method for generating x-rays or gamma rays via laser Compton scattering, comprising: producing a continuous wave (CW) laser beam; modulating said CW laser beam at a multi-GHz radio frequency (RF) to produce a modulated beam; utilizing said modulated beam to provide electron micro bunches at said radio frequency (RF), wherein said RF is the operating RF of a linear accelerator that provides said bunches, wherein said bunches are directed to propagate, with radio frequency spacing between successive said bunches, within a first confocal region, wherein said first confocal region is produced by focusing said electron micro bunches; and utilizing said modulated beam to provide laser pulses at said RF, wherein each laser pulse of said laser pulses has a pulse duration within the range of 10 ps to 1 fs, wherein said pulses are directed to propagate, with radio frequency spacing between successive said pulses, within a second confocal region, wherein said second confocal region is produced by focusing said laser pulses, wherein said first confocal region and said second confocal region intersect in an interaction region such that said electron micro bunches collide with said laser pulses to generate incoherent x-rays or gamma-rays via laser Compton scattering, wherein the pulse duration of each laser pulse of said laser pulses is of the order of the transit time of each laser pulse through said second confocal region and wherein the pulse duration of each electron micro bunch of said electron micro bunches is of the order of the transit time of each laser pulse of said laser pulses through said second confocal region.
