This book was released on 1978 with total page 146 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 lifetimes of XeF and KrF were measured by the photolytic dissociation of XeF2 and KrF2 respectively. In addition quenching rate constants and radiative lifetimes are used in a code to predict laser performance of both XeF and KrF. A description of the code is given. Experimentally further efforts have been made to measure optical absorption in the XeF laser and to improve performance by investigating the role of the diluent gas. In other work, an excited metal-rare gas mixture was investigated to evaluate them as laser candidates. Finally quenching measurements of Ba were begun. If high values are obtained for the quenching measurements, there is a possibility that a Ba-N2O electronic state chemical laser can be made. (Author).

This book was released on 1976 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The DARPA-NRL Laser Program is concerned with the development of laser technology with the emphasis on electronic state lasers and the associated physics. Electrically excited infrared lasers and intramolecular energy transfer are also being studied. Progress is reported in all areas with the major highlights being (1) the observation of quasi-CW lasing in XeF (2) the discovery of the KrCl laser at 223 nm (3) advancement of discharge-pumped rare-gas halide lasers and their understanding, and (4) improvements in the performance of the CO-C2H2 and CO-CS2 energy transfer lasers which are being studied in the electric-discharge gasdynamic laser facility.

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.

This book was released on 1976 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The DARPA-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 includes studies of pulsed HCl laser systems and molecular energy transfer processes. Several chlorinated hydrocarbons have been identified as attractive chlorine sources for HCl lasers based on the Cl + HI reaction. Vibrational relaxation rates for the CO laser and the potential D2 yields HCl V-V transfer laser system have been measured. The electical infrared program emphasizes electric-discharge gasdynamic lasers and electron-beam pumping of potential laser systems in the mid infrared. Studies of the D2 yields HCl system have been continued along with detailed measurements of the discharge and flow characteristics. The D2-CO2 laser system previously discovered has been found to have comparable efficiency to the N2-CO2 EDGDL. A number of excitation approaches are being evaluated for application to electronic state lasers. Discovery of the XeBr laser as a result of electron-beam excitation of Xe/Br2 mixtures has led to the rare-gas halide laser systems. Successful transverse excitation of copper chloride offers promise as a more efficient copper vapor laser. Electrical and optical pumping schemes to extend the range of operation of the previously reported Hg vapor laser are described.
