On a Gasdynamic Recombination Laser.
Abstract
The possibility is discussed of a gasdynamic laser using dissociation as the frozen mode, rather than vibration, and which would lase following recombination. Such a laser has the potential of high power, high efficiency, and visible wavelengths. Several reactions are considered, and recombination to form molecular bromine, chlorine and nitrogen dioxide were considered most suitable. Calculations of expected gain are presented. Unfortunately rapid deactivation by atoms destroys the promise of the chlorine and bromine systems. Experiments performed in a shock tunnel generated no laser action in either chlorine or nitrogen dioxide. Recombination to molecular oxygen does not suffer from deactivation by atoms, but has too low a gain to achieve laser action in the apparatus available.
