Spectroscopic and Infrared Measurements on CW HF (DF) Chemical Lasers.
Abstract
The supersonic, free-jet medium of a 10 to 15 kW, HF/DF chemical laser is studied. Results from a remotely controlled spectrograph that scans rapidly, spatially, and spectrally are described; observations from an IR vidicon system are also given. The laser system includes two types of plenum gas heater: arc and combustor; and two types of nozzle bank: split and axisymmetric. The spectrograph measures the HF 3-0 P-branch emission, from which HF(3) number density along the line-of-sight N3L and rotational temperature T(R) are deduced at a large number of spatial positions. The data can be given as three types: (1) spatial scans transverse to the flow, (2) scans parallel to the flow, and (3) data at fixed position. Various interpretations concerning the medium result from the three types of data.
