We consider the implementation of a patented source of pulsed laser radiation, which allows economical use of power owing to the original structure of a parallel set of optical delay lines and the addition of the amplitudes of the pulses of the input laser radiation. The results of a computer experiment for different numbers of switching channels with the determination of the predicted output peak power of the laser source are presented. To assess the radiation source, the concept of system efficiency is introduced as the ratio of the output peak power to the number of channels of delay lines. The results of the calculations are presented in the form of efficiency graphs for different numbers of channels, considering losses in the optical fiber lines of the optical delay. The proposed source of pulsed laser radiation can potentially be used in optical communication lines, laser data systems, and medical devices.
