Bremsstrahlung emission from laser - produced plasmas

Abstract
The x‐ray bremsstrahlung from 4 to 50 keV emitted by laser‐produced plasmas has been measured using a Bragg crystal spectrometer. Direct spectral information was obtained in contrast to earlier filter spectroscopy.Measurements were made with focal spot powers of 1016 W/cm2 of 1.06‐μm radiation and 1014 W/cm2 of 10.6‐μm radiation. A definite suprathermal electron component was observed.
