Phosphorus Chemiluminescence Feasibility Studies for an Ultraviolet and Visible Chemical Laser.
Abstract
The aim of this project was to explore whether an inverted population of electronically excited species either, (1) exists among the intermediates of the phosphorus chemiluminescence reaction or, (2) can be generated by excitation of atomic and molecular species added to the flame. In an investigation of laser light amplification on traversing phosphorus chemiluminescent flames using light in the 280-500 nm region, under certain conditions there is suggestion of amplification but because of the scattering at the interfaces no definite conclusion can be drawn. In the chemi-excitation experiments the two emission lines at 5787 and 5806 A which we have tentatively assigned as excited state - excited state transitions of K are good candidates for lasing. The other emissions, the 5765 3A emission tentatively assigned to NaK and the Na and K doublets have lasing potential depending on the mechanism of excitation. The phosphorus flame and the atomic and molecular composition of the NaK stream are extremely susceptible to pressure and temperature changes and, as in the light amplification studies, the obvious next step is to confine the system in a heat pipe oven where these variables can be strictly controlled.
