Imaging and modeling nonlinear ionization dynamics in a hot dense plasma

Caption

A strong infrared (IR) laser pulse creates a highly ionized plasma channel in a krypton target. An extreme ultraviolet (XUV) probe or seed pulse is sent through the plasma channel. A diffraction imaging setup using a nanoscale target enables taking a high-resolution image of the XUV beam. A four-dimensional Maxwell-Bloch model numerically calculates the laser-matter interaction in the plasma channel and allows calculating the spatially and time-dependent electron density as well as ion abundance in the plasma channel.
