Characterization of a Pulsed HF Optical Resonance Transfer Laser.
Abstract
The HF (v=2) vibrational level was pumped optically on the P2(8) transition and P2(7) transition. The 0.5 percent HF in helium gas at 50 torr was pumped by an HF laser with 0.081 joules per pulse and 96 pulses per second. The technique involves observation of absorption by HF (v=2). Decreased absorption was observed on the P2(8) transition implying the possibility of gain by V-V exchange. The data shows conformance with the results of a previous investigation on the P2(8) line. Interrogation of the P2(7) transition failed to yield conclusive results due to a poor signal to noise ratio. A theoretical model of the kinetics of the HF V-V and V-T exchanges was established. Pulse shapes predicted by this theory and those observed experimentally for the P2(8) line agree well. Excessive noise levels precluded investigation of other transitions. (Author)
