All existing x-ray dispersive devices including crystals, multilayers and diffraction gratings generate spectra in multiple orders.In this presentation we r
Wavelength scaling law for the yield of high-order harmonic emission is theoretically examined for excited state atoms which are optically prepared by simul
Because the refractive index of unmagnetized uniform plasmas is approximately expressed as n =(1-ω2p0 / ω2)1/2 and the electron velocity v < c in the limi
