Research in laser processes
Abstract
Measurements have been made of the electrical and optical properties of electrical discharges in Mg-Xe mixtures at moderate current densities (50-100 A/cm to the 2nd power) and high Xe pressures (1 to 5 atmospheres). Preliminary analyses indicate a rather low electron and excitation temperature resulting from unexplained large energy losses. Efforts to obtain the high excitation temperatures required for efficient, high power excimer laser operation will continue. An experiment is being designed to provide effective rate coefficients for electron excitation and deexcitation of excited mercury atoms so as to provide data necessary for the modeling of the contribution of these states to the production of upper laser levels and to the growth of ionization and instabilities in discharge excited lasers. This experiment will use laser induced perturbation of the excited state densities and optical observation of the relaxation of excited state densities.
