Semiannual Technical Report to Defense Advanced Research Projects Agency - 1 July 1974-31 December 1974 written by NAVAL RESEARCH LAB WASHINGTON D C. and published by . This book was released on 1975 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program is concerned with three project areas: Chemical Infrared Lasers, Electrical Infrared Lasers and Electronic State Lasers. The Chemical Infrared Laser Program is concerned with the development of pulsed HCl laser systems and the study of molecular energy transfer processes. Several new sources of Cl atoms have been identified that lead to improved HCl laser performance. Low-temperature vibrational relaxation measurements in CO2 mixtures indicate a minimum in the relaxation rates near room temperature. The Electrical Infrared Program emphasizes electric-discharge-gasdynamic lasers and electron-beam pumping of potential laser systems in the mid infrared. Energy transfer has been observed in the D2*-HCl system and a D2*-CO2 laser has been developed. A number of excitation approaches are being evaluated for application to Electronic State Lasers. Studies of direct electron-beam excitation of the Ar*-N2 laser have been completed and a sophisticated model for electron energy deposition has been developed. Optical pumping techniques, as used in the previously reported Hg vapor laser, are being extended to other atomic systems. Studies of the Hg vapor laser are essentially complete and reported here in detail. A transverse discharge Cu vapor laser has been assembled and is being tested.

This book was released on 1975 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second semiannual technical report for the ARPA/NRL X-ray Laser Program. The individual activities in the program include: electron collisional pumping using picosecond laser heating of a cold plasma; traveling wave (TW) high energy electron beam pumping; nonlinear optical mixing starting with intense 1600 A radiation; resonant charge transfer pumping using a laser plasma expanding into a neutral gas background, and theory, analysis, and numerical modeling in support of the above and other approaches. Some reprints of completed papers are included.

This book was released on 1975 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ARPA-NRL Laser Program is concerned with the development of laser technology in three project areas: Chemical Infrared Lasers, Electrical Infrared Lasers and Electronic State Lasers. The Chemical Infrared Laser Program is focussed on DF-CO2 supersonic transfer laser experiments designed to evaluate chemical augmentation of gas dynamic lasers. Augmentation has been observed but is limited by deactivation processes. The temperature dependence of energy transfer processes in CO, CO2, and N2O has been measured. The Electrical Infrared Laser Program has two primary projects, short-pulse CO2 laser technology and electric-discharge gas dynamic lasers (EDGDL). The short pulse laser project has successfully been completed culminating in reliable 70 J single-pulse operation. A compact high-pressure e-beam-controlled CO2 laser has been developed for the generation of picosecond laser pulses. Infrared fluorescence from HCl generated by energy transfer from vibrationally excited D2 has been measured.

This book was released on 1977 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The DARPA-NRL Laser Program is concerned with the development of laser technology of electronic state lasers and associated physics. In particular the development of the XeF laser has been emphasized. Experimental and theoretical efforts were made to understand and improve laser performance. The radiative lifetime of XeF was measured by photolytic dissociation of XeF2. A short pulse electron beam device was set up to remeasure the XeF lifetime more accurately and work was started to synthesize KrF2 in order to measure the lifetime of KrF. Values for the radiative lifetime are used in a code to predict laser performance of both XeF and KrF. Experimentally the performance of the XeF laser has been improved. Long laser pulses were observed for the first time and laser efficiency was increased by substitution of Ne for Ar, the diluent. Absorption measurements combined with code calculations showed that the improvement was due to decreased dimer ion optical absorption.
