A., et al., Focusing the Beam of a Compact, Repetitively Pulsed X-Ray Laser to Study the Interaction of Radiation with Metallic Targets and X-Ray Reflectometry, Quantum Electronics 30, no. 4 (2000): 328-332.http://hdl.handle.net/10217/67521The interaction of focused soft x-ray laser radiation with metallic targets was studied experimentally. The radiation of a capillary-discharge Ne-like Ar ion laser (λ = 46.9 nm) with a repetition rate of 1 Hz was focused on the surface of metallic samples by using a spherical Si/Sc multilayer mirror. The radiation intensity at the target surface was far greater than the threshold for laser ablation of the materials in use - aluminum, brass, and stainless steel. A study of the shape of laser craters in relation to the position of the caustic of the focusing mirror, combined with computer ray-tracing simulations, made it possible to determine the radiation intensity distribution in the focal region of the mirror. The radiation energy density in the 2 μm central domain of the focal spot was 102 J cm-2, and the corresponding intensity was 1011 W cm-2. The reflectivity of a Si/Sc multilayer mirror was measured as a function of the angle of incidence of the radiation.born digitalarticleseng©2000 Kvantovaya Elektronika and Turpion Ltd.Copyright and other restrictions may apply.
