Imaging of laser-produced plasmas at wavelengths of 130 A and 34 A using a microscope with multilayer-coated mirrors

摘要

Laser-produced plasmas were imaged using a microscope consisting of spherical primary and secondary mirrors that were coated with 40 Mo/Si periods and had peak reflectance of 60% at a wavelength of 130 angstroms. Niobium, gold, and aluminum targets were irradiated by up to 24 beams of the Omega laser at the Laboratory for Laser Energetics at the University of Rochester. Magnified images were recorded on Kodak 101 film, and the resolution was limited by the 10 $mu@m emulsion grain size. A variety of plasma emission features were recorded with 5 $mu@m (0.6 arcsec) resolution in the object plane.
