A novel hard X-ray source has been developed that is intense, quasi-monochromatic, and compact enough to allow the modest laboratory use in a ubiquitous fashion. The measurement by hard X-ray spectroscopy from the Ar gas target irradiated by 60 fs, 200 mJ Ti:Sapphire laser pulse at 10 $^{17}$ W/cm $^{2}$ yields brilliant high phase-contrast imaging of a small animal. The X-ray spectrum has a characteristic of Ka emission having unusually compressed continuum and vanished energetic X-ray tail with the emission intensity of Ar line of 10 $^{10}$ photons (4p sr pulse)-1.
