Abstract

A broadband continuous-wave dye laser has been enclosed to eliminate interfering atmospheric absorption, and has been run at pressures as low as 50 Torr of various gases. Detection of peak absorption coefficients as small as 10-8 cm-1 has been verified, and lines spaced by 0.1 cm-1 have been resolved.
