ELECTRON-ATTACHING GASES IN LASER DISCHARGES : ALTERED DISCHARGE PARAMETERS AND NEGATIVE-ION PRODUCTION

Abstract
Two very important parameters of a laser discharge which affect the excitation rates and laser kinetics as well as the "quality" of the discharge are the electric-field-to-pressure ratio, E/P, and the preionization. The addition of an electron-attaching gas to the laser mix can strongly modify both of these parameters. By properly accounting for the changes in these discharge parameters, changes in the laser kinetics and emission can be correctly predicted. Two exemplary cases are considered: the addition of SF6 to N2 lasers, and preionization effects in eximer lasers.
