Electron-Beam-Sustained Blue/Green Laser Pump.

Abstract

Techniques are described for prolonging the duration of stable e-beam controlled excimer laser discharges, including: temporal tailoring of either the discharge voltage or the ionization source, and kinetics modification by way of additives. Theoretical and experimental results are presented for KrF* discharges. XeCl(B) formation processes are examined for conditions typical of a discharge excited laser using HCl as the chlorine donor. It is shown that vibrational excitation of HCl followed by dissociative attachment is a primary step in the reaction sequence resulting in cl(=). XeCl(B) formation is the result of a three-body Xe(+) - Cl(=) recombination reaction. Experimental results are presented which demonstrate efficient (about 2%) XeCl laser operation in an e-beam assisted discharge in which over 75% of the energy was deposited by the discharge.
