K-shell emission of highly-ionized copper from relativistically-intense laser pulses

ORAL

Abstract

We will discuss our recent work performing high-resolution (E/ΔE > 5000) X-ray spectroscopy of copper K-shell emission from high-intensity (I ∼1021 W/cm2) laser experiments using the high contrast (> 10-11) ALEPH 400 nm laser at Colorado State University. Through simultaneous measurement of front- and rear-side K-shell fluorescence and accompanying collisional-radiative modeling we examine the generation and propagation of energetic electrons in thin foil and layered targets to elucidate the physics of ultra high-intensity, laser-solid interactions.
