Abstract : A high power CO2 laser (50 J in a 50-ns-wide pulse) was used to produce a plasma by irradiating a plane target. The X-ray emission characteristics of this laser-produced plasma were studied to check the utility of such a plasma as an X-ray source for simulation purposes. The reflectivity of the incident 10.6-micrometer-wavelength laser radiation by the laser-produced plasma was also investigated. The experimental results were analyzed using the theory for laser-produced plasmas.
