Title: Phase-contrast x-ray imaging with intense Ar K{alpha} radiation from femtosecond-laser-driven gas target

Abstract

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.

  • Bright Ar quasimonochromatic K-shell x ray with very little background has been generated using an Ar clustering gas jet target irradiated with a 30 fs ultrahigh-contrast laser, with a measured flux of 2.2x10{sup 11} photons/J into 4{pi}. This intense x-ray source critically depends on the laser contrast and intensity. The optimization of source output with interaction length is addressed. Simulations point to a nonlinear resonant mechanism of electron heating during the early stage of laser interaction, resulting in enhanced x-ray emission. The x-ray pulse duration is expected to be only 10 fs, opening the possibility for single-shot ultrafast keV x-raymore » imaging applications.« less
  • We show that x-rays from a recently demonstrated table top source of bright, ultrafast, coherent synchrotron radiation [Kneip et al., Nat. Phys. 6, 980 (2010)] can be applied to phase contrast imaging of biological specimens. Our scheme is based on focusing a high power short pulse laser in a tenuous gas jet, setting up a plasma wakefield accelerator that accelerates and wiggles electrons analogously to a conventional synchrotron, but on the centimeter rather than tens of meter scale. We use the scheme to record absorption and phase contrast images of a tetra fish, damselfly and yellow jacket, in particular highlightingmore » the contrast enhancement achievable with the simple propagation technique of phase contrast imaging. Coherence and ultrafast pulse duration will allow for the study of various aspects of biomechanics.« less
  • The high-intensive source of soft X-ray emission was developed by femtosecond laser pulses irradiation of submicron size CO{sub 2} clusters, produced in custom designed super-sonic nozzle while mixing the 10% CO{sub 2}+90% He expanding gases. The LiF crystal soft X-ray detectors have been used for obtaining absorption images of ultrathin (nanoscale) foils and biological structures illuminated by the developed source. It was demonstrated that even if the foil is essentially transparent for the soft X-ray radiation (like 100 nm thick Zr foil), the image contrast could be significantly increased due to the influence of propagation-based phase-contrast effect, by placing themore » detector at the proper distance from the sample.« less
  • Application of polychromatic (1.5-15 nm) soft X-ray emission of a spatially large (>0.1 mm) bright femtosecond laser driven plasma source for propagation based phase contrast imaging of nanometer thick foils and biological samples is considered. Diffraction and phase contrast effects increased quality and contrast of the experimental images, registered by LiF crystal X-ray detector with submicron resolution.
  • We report a continuously operated Cu K{alpha} x-ray source produced by a commercial kilohertz submillijoule femtosecond laser system. The source has an x-ray conversion of {approx}4x10{sup -5} into K{alpha} line emission at 8.05 keV. The microplasma x-ray source has a size of 8 {mu}m (full width at half maximum) produced by focusing 260 {mu}J laser pulses on a moving Cu-wire target. An average photon flux of {approx}1.1x10{sup 9} photons/sr/s is obtained using the above laser pulses. The source has been used to record phase contrast images of test samples. This compact x-ray source can serve as a low cost operatingmore » system for phase contrast imaging in clinical applications.« less
