Molecular and Chemical Laser Systems.
Abstract
The work performed under the above referenced grants included: (a) Experimental study of the reaction system O + HI yielding OH + I or I* and O2('delta g) + I(2P3/2) in equilibrium with O2(3 sigma 9) + I*(2P1/2) in a flow system. Measurements of optical gain at the I atom laser wavelength of 1.315 microns indicated an optical loss of 3-8% across the transverse flow laser channel. (b) Parametric studies were made on a variety of compounds suitable for photodissociative pumping of I atom lasers. (c) Spontaneous mode locking was observed and experimentally studied in a photolytically pumped I atom probe laser. (d) Electronic to vibrational energy transfer between O2*('delta g) and HF leading to the vibrational excitation of HF to levels v=1 and v=2 was observed and studied. Evidence was provided that the transfer occurs from O2('delta g) rather than from O2('sigma +g). (Author)
