Abstract

Laser frequency-modulated (FM) spectroscopy has been used as an axial probe of a laser-guided electric discharge in sodium-argon vapor contained in an optically accessible metal heat pipe oven. Absorption measurements in the region 23 106-23 881 cm^-1 provided accurate line positions (±<0.006 cm^-1) for 141 transitions in the ν′ = 3-8 ← ν″ = 0 and ν′ = 5-9 ← ν″ = 1 bands of NaH (Α¹Σ⁺ - Χ¹Σ⁺). In addition, 18 transitions of Na (3p to 9-13d and 11-14s) and 10 of argon (5p-4s) were measured. Analysis of the spectrum indicates that perhaps all absorption signals are due to neutrals NaH, Na, and Ar and are observed via "population" modulation.
