Abstract : Laser emission from atomic nitrogen at 1.3583 micrometers, carbon at 1.4543 micrometers, chlorine at 1.5871 micrometers and 2.4466 micrometers, and fluorine at 0.7131 micrometers and 0.7041 micrometers has been observed in a pulsed electrical discharge through flowing mixtures of a parent compound (N2, NO, N2O, NO2, ClNO, NH3, NF3, CO, CO2, OCS, CS2, C2H2, C2H5OH, or CCl4) and helium. The emission appeared as one or more peaks at each wavelength. In many cases the number of peaks in the laser signal depended on the pulse repetition rate, peak current, and the parent-compound-to-helium pressure ratio. (Author)
