The transient emission of VUV laser radiation from the carbon-like ionization stage of a laser-heated argon plasma is calculated. The plasma is taken to be spherical in shape, of uniform ion density, and to be uniformly heated by short pulses of laser energy, which are absorbed by the plasma electrons.Excitation of the carbon-like ionization stage is controlled by the trapping of resonance line radiation within the ionization stage. Two resonance lines, along with the VUV laser line, are self-consistently coupled to the rate equations describing the excitation dynamics of the argon plasma. Some effects of this coupling on the output of amplified spontaneous VUV emission are determined by comparing population densities, gain coefficients, and VUV laser power output as functions of time for a number of different cases in which the amount of radiation coupling to the plasma is varied.
