A high Mach number, radiatively cooled jet of astrophysical interest has been produced using intense laser irradiation of a gold cone. The evolution of the jet was imaged in emission and in radiography, and the temperature was measured with Thomson scattering. Comparison with numerical simulations shows that radiative cooling is a dominant mechanism in the collapse of the Au plasma jet on axis, with temperatures plummeting and peak densities increasing, each by an order of magnitude in ˜1/2 ns. In dimensionless terms, aspects of this jet are similar to radiative astrophysical jets.
