Abstract

A high power (200 J, 50 ns) 249-nm KrF laser has been focused onto solid Al targets in vacuum at a peak irradiance of 3 multiplied by 10**1**3 W cm** minus **2. High-temperature ( greater than 200 eV) plasmas are produced and x-ray measurements show intense emission of the resonance spectra of Al XII and Al XIII in the wavelength range 0. 6-0. 8 nm. Absolute x-ray intensity measurements indicate a maximum source brightness of 1. 1 multiplied by 10**1**7 erg cm** minus **2 s** minus **1 sterad ** minus **1 in DELTA v/v equals 10** minus **3 and a conversion efficiency from laser power to x-ray power of 0. 2% for 1. 5 keV less than hv less than 2. 5 keV.
