Abstract

In our work we considered efficiency of pulse train generation in Q-switched lasers excited with rectangular pulses. It was proved that such a generation efficiency is significantly higher than efficiency of monopulses generation, especially for three-level lasers. For four-level lasers, an increase in efficiency of pulse train generation appears for the active materials for which depopulation time of the lower laser level is longer in comparison with generation time. Such efficiency increase is observed also for the Nd:YAG lasers. It was confirmed experimentally for diode pumped passive Q-switched Nd:YAG laser.
