Abstract

A small cw mixing laser operating on a single wavelength and tunable over about 400 MHz was used to measure absorption coefficients for HF and DF in the Doppler-broadened region and for HF in the pressure-broadened regime. At low pressure, the line profile was experimentally determined and from measurements at line center, values were obtained for the radiative lifetime of HF and DF of 6.16 × 10⁻³ s and 3.13 × 10⁻³ s, respectively. High-pressure measurements yielded the value of 1.30 × 10⁸ s⁻¹ torr⁻¹ for the HF optical-broadening collision frequency.
