Abstract
Calibrated thermoluminescence dosimeters have been used to measure the angular and spectral dependence of hard x‐ray emission produced from intense subpicosecond laser irradiation of solid targets. A dosimeter detector set with nine filter channels (13.5–400 keV) has been tested successfully. Total bremsstrahlung conversion up to 0.23% and conversion of 8×10−5 from laser energy to Ta Kα line emission (photon energy ≊57 keV) was determined. The scaling of the hard x‐ray yield with laser intensities ranging from 3×1016 to 3×1018 W/cm2 was investigated.This publication has 16 references indexed in Scilit:
