A X-ray source, comprising a laser, of a pulse duration of at most 40 fs, instantaneous power of at least about 80 TW, a pulse repetition rate of at least 1 Hz; an optical compressor spectrally shaping the laser beam; focusing optics in the range between f#10 and f#15; and a gas target of electron density after ionization by the laser beam in a range between 10cmand 10cm; wherein the focusing optics focuses the laser beam in the gas target, and interaction of the focused laser beam with the gas target generates an X-ray beam, with a focused laser amplitude a, given by a=0.855 [I(10W/cm)&#x3bb;,(&#x3bc;m)], where Iis the on-target laser intensity and &#x3bb;is the laser wavelength, of at least 2 and a P/Pratio value of at least 20, with P being the beam power and Pc a critical power given by Pc=17 (n/n) GW where n is the electron density and nis a critical electron density at which the plasma acts as a mirror reflecting the laser beam.
