Abstract
The high‐energy continuum x‐ray emission from plasma created by intense (1014 W cm−2) nanosecond 10‐μm laser pulses has been characterized. The temperature of the superthermal electron component deduced from this emission was found to be strongly dependent on focus position, while displaying a weaker dependence on irradiation angle, beam polarization, and target composition. The variation of the hot‐electron temperature as a function of Iλ2 has been examined in detail in a range of Iλ2 from 1015 to 2×1016 W μm2 cm−2 for various target materials and has been found to be in qualitative agreement with the predictions of current theories of hot‐electron production based on resonance absorption.This publication has 31 references indexed in Scilit:
