Paper Abstract

Interferometric measurements of the transient refractive index in electron-beam-pumped Ne/Xe/NF3, Ne/Xe, and Ne/NF3 mixtures are reported. The measured fringe shift in the Ne/Xe/NF3 laser mixture at 351 nm is + 5 rad over a 2 m path at an energy loading of 70 J/f, indicating an increase in the refractive index. Energy flow pathway kinetics used in conjunction with fringe shift measurements suggest that the observed shift is due to XeF(B2I1,2). The implications of these measurements for obtaining near- diffraction-limited beam quality in an electron-beam-pumped XeF laser are discussed.
