Monochromatic X-ray generation from Cu plates was experimentally studied by using a high contrast femtosecond laser pulse. Absolute yield of Ka line at 8 keV was measured as a function of laser pulse contrast ration and irradiation intensity. The conversion efficiency of 8 $$times$$ 10$$^{-5}$$/sr, the highest value ever obtained, has been demonstrated at 5.5 $$times$$ 10$$^{16}$$ W/cm$$^{2}$$ with a contrast ratio of 10$$^{-11}$$.
