Paper Abstract

The output of the Phillips Laboratory's CO2 Electric Discharge Coaxial Laser (EDCL II) is a nominal 13.2 centimeter diameter beam with over one hundred transverse modes and a divergence of over ten milliradians at forty kilowatts. In support of a critical test series, several resonator configurations were examined to reduce the output beam divergence to facilitate production of a beam on-target of 0.005 X 1.0 inches with high irradiance. Resonator reconfiguration of EDCL II with the associated beam shaping optical train and measured experimental results are discussed.
