Bright Ar K-shell x-ray with very little background has been generated using an Ar clustering gas jet target irradiated with an 800 mJ, 30 fs ultra-high contrast laser, with the measured flux of 1.1 x 10^4 photons/mrad^2/pulse. This intense…
X-ray microtomography at synchrotron sources is fundamentally limited by the high radiation dose applied to the samples, which restricts investigations to non-native tissue states and thereby compromises the biological relevance of the…

A scheme of soft-xray radiation is proposed. In the scheme, a moderately intense laser excites plasmons via the two-plasmon decay in a relativistic electron beam. As the second laser encounters the electron beam in the opposite direction,…
