Abstract

The results of experimental study of the pump intensity and active media parameters effect on output energy and efficiency of a discharge-pumped ArF (193 nm) excimer laser on a mixture of He:Ar:F₂ are presented. It was experimentally shown that for the achievement of maximal output energy with maximal efficiency of an ArF excimer laser it is necessary to use an optimal pump intensity of 4.5-5.0 MW/cm³. To achieve such active media pump intensity the excitation scheme of the LC-inverter type has been used where the energy losses inside discharge circuit had been decreased. Using the pump intensity of 5.0 MW/cm³ in an active media of He:Ar:F₂ - 79.7:20:0.3 at total pressure of 2.4 atm the output energy of 1.3 J at the total efficiency of 2.0% was obtained for the first time.
