Abstract

A two-beam differential laser absorption technique is used to measure U238 absorption spectra with high signal-to-noise ratios in an atmospheric pressure laser-induced plasma. High-resolution absorption spectra are presented for the U238 861 nm transition in the presence of dry air at pressures up to 760 Torr. A spectral linewidth (FWHM) of 2.23±0.13GHz was found for the U238 line in dry air at 760 Torr. Absorption spectrum measurements using a low U238 concentration NIST glass standard were used to demonstrate sensitivity of the approach.
