Abstract:
1. A method for generating ultrabright multikilovolt coherent tunable radiation in the x-ray region of the electromagnetic spectrum, comprising: (a) generating pulsed laser radiation having a chosen power, pulsewidth and wavelength; (b) generating atomic clusters having a chosen size and density; (c) directing the laser radiation into the atomic clusters wherein rapid atomic excitation is generated having selected inner-shell electron atomic electrons being removed from the atoms without the removal of all of the electrons in the next outermost shell, thereby generating a population inversion from which a chosen wavelength of radiation is amplified or spontaneously generated in the x-ray region of the electromagnetic spectrum, and wherein the generated or amplified radiation is propagated in a self-trapped plasma channel region additionally having a nonlinear mode of confined propagation for the chosen wavelength of radiation; and (d) simultaneously controlling the density of said atomic clusters, the density of plasma electrons, and the laser radiation such that the wavelength of amplification is defined.
