NITROGEN LASER POWER DENSITY AND SOME DESIGN CONSIDERATIONS

Abstract

The laser power density and its time history from a pulsed molecular nitrogen laser were calculated using the theory of Ali, Kolb, and Anderson. The dependence of the power density and its duration on the fill pressure and on various parameters of an electric circuit, in which the nitrogen gas acts as a variable resistor, was examined. It is known that the peak power density increases in a circuit with low inductance and high capacitor voltage and that the energy density is optimum at a fill pressure of approximately 30 Torr. Based on these premises and the gain calculations, some design considerations were also studied.
