Abstract

Experiments have been performed to determine the effect of laser-pulse duration and energy on hot-electron-generation efficiency at high intensity. Thin copper foil targets were irradiated with 1 to 2100 J, 1 to 10 ps pulses focused to intensities 10¹⁸ Wcm². The target volume was varied from 75×75×3 m³ to 600 600 50 m³ to access a range of bulk thermal-electron temperatures up to several hundred electron volts. Comparison of K-photon spectroscopy measurements from these targets with electron transport and radiation-generation calculations indicates that the energy conversion efficiency into hot electrons is 20±10, independent of laser-pulse duration and energy.
