The efficiency of copper vapor laser (CVL) excitation by a pulse with a short rise time and aperiodic current behavior disrupted at the moment of output pulse termination has been investigated experimentally. Under these conditions of excitation, the efficiency of a CVL is demonstrated to reach ~9%. Preliminary data on processes in the discharge plasma are presented. Based on the results obtained a method of output pulse shape and duration control for CVL has been developed. Reduction of the output beam divergence down to the diffraction limit has been investigated, and an increase of the reduction efficiency from 28% to 83% has been achieved when using the regime of output control instead of a conventional regime. A three time narrower emission spectrum of a dye laser pumped with a CVL operating in the regime of a pulse shape control has been achieved.
