Title: Conversion efficiency of extreme ultraviolet radiation in laser-produced plasmas

Abstract

A simple analytical model is presented for the conversion of laser beam energy into extreme ultraviolet radiation. The model is compared with experimental results to show good agreements under different conditions of the laser wavelength {lambda}{sub L}, the laser intensity S{sub L}, the pulse duration t{sub L}, and the target atomic number Z{sub 0}. It turns out that relatively high conversion efficiencies are obtained when the Planck optical thickness of the plasma is {tau}{approx_equal}0.3-0.5, which is attained under an optimized combination of S{sub L} and t{sub L} once {lambda}{sub L} is fixed. The {lambda}{sub L} scaling on the conversion efficiency is derived.
