Popis: The x-ray spectrum emitted by a gas jet irradiated at ${10}^{16}$ W/${\mathrm{cm}}^{2}$ has been measured for laser wavelengths of 1.05 and 0.53 \ensuremath{\mu}m. The flux of hard x rays ($h\ensuremath{\nu}g~10$ 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.
