Intense Ar K{alpha} x ray with very little continuum background has been generated using a dense Ar gas irradiated with an intense femtosecond laser, with the measured flux of 1.2x10{sup 3} photons/mrad{sup 2}/pulse. This compact quasimonochromatic x-ray source, with a source size of only 12 {mu}m, has been applied to x-ray radiographic imaging of a biological specimen, resulting in high-resolution, high quality phase-contrast images. Correlation between this intense K{alpha} emission with the laser channeling in the Ar gas is discussed.
