Abstract:
The time-dependent output spectrum of a helium-diluted H2-F2 chain reaction chemical laser has been observed. Reaction of a 50-Toor mixture with mole ratio H2F2He - 1160 was initiated by flash photolysis of the F2. Strong lasing was found from P-branch vibration-rotation transitions of the v 1 to 0, 2 to 1, 3 to 2, and 4 to 3 bands of HF. Within some bands, the time sequence of transitions suggests non-Boltzmann distributions of rotational states. No lasing from vibrational levels higher than 4 could be detected.
