High brightness keV harmonics from relativistically oscillating plasma surfaces
X-ray harmonic radiation extending to 3.3 Å, 3.8 keV from Petawatt class laser-solid interactions is presented. The harmonic spectra display a relativistic limit scaling up to ∼3000th order, above which an intensity dependent scaling roll-over is observed. Highly directional beamed emission for harm...

| description | X-ray harmonic radiation extending to 3.3 Å, 3.8 keV from Petawatt class laser-solid interactions is presented. The harmonic spectra display a relativistic limit scaling up to ∼3000th order, above which an intensity dependent scaling roll-over is observed. Highly directional beamed emission for harmonic photon energy hv > 1 keV is found to be into a cone angle < 4°, significantly less than that of the incident laser cone (20°). © EDP Sciences and Springer 2009. |
