Abstract
The chemiluminescence spectrum in the optical cavity of discharge-driven
hydrogen fluoride (HF) chemical laser is measured. The result reveals that the
spectra of the helium and fluorine (F) atoms are the major components. Moreover, the
green chemiluminescence in the downstream of the optical axis is mostly composed of
the 60P20 spectral line of the HF molecule. The analysis shows that, except for the
cold pumping reaction, the recombination of the F atoms and the hot pumping reaction
also occur in the optical cavity. Due to the hot pumping reaction and the optical
cavity temperature in a specific range, the 60P20 line becomes the strongest HF
molecule in the downstream region of the optical axis. After the hot pumping
reaction, the green chemiluminescence always appears in the downstream region of the
optical axis when the optical cavity temperature varies in a greater range.
