Abstract

The x-ray spectrum emitted by a gas jet irradiated at 1016 W/cm2 has been measured for laser wavelengths of 1.05 and 0.53 m. The flux of hard x rays (h>10 keV) emitted by a gas jet is less than 0.3% of that emitted by a glass target irradiated at the same intensity. This low flux implies that less than 0.1% of the incident energy is used to heat electrons to energies greater than 10 keV.
