摘要：

X-ray conversion efficiencies in 351-nm laser-produced plasmas are investigated. X-ray line emissions, which are useful for x-ray shadowgraphy, have been characterized by studying dependencies on laser pulse duration, irradiation intensity, target material, and target structure. The conversion efficiencies decrease with increasing x-ray energy and markedly decrease with increasing laser intensity. A microparticle on a plastic plate is tested in an attempt to develop a point x-ray source. This target shows a higher conversion rate than a microwire target due to reduction in energy dissipation through hydrodynamic expansion.
