UV Gas Laser Investigations

Abstract

A peak laser power of 0.5 MW with an estimated efficiency of 0.2% has been obtained at 3577A from a mixture of 92 psia Ar and 8 psia N2 which was excited by an E-beam of 400A/cm squared at 1.3 MeV in a 20 ns pulse. A saturation intensity of about 100 kW/cm squared was deduced and a beam divergence of 10 milliradian was measured from the laser having a 10 cm gain length.
