ARPA/NRL X-Ray Laser Program - Semiannual Technical Report to Defense Advanced Research Projects Agency, 1 January 1974 - 30 June 1974

Abstract : The ARPA/NRL x-ray laser program is concerned with demonstrating gain in the soft x-ray region. The program is jointly supported by ARPA and NRL. The approaches include electron-collisional pumping in picosecond laser pumped plasma, resonant charge transfer pumping, optical parametric mixing to short wavelengths, traveling wave e-beam pumping, and analysis and numerical modeling. This report covers the progress made during the second half of FY-74.
