In this study, the mechanism of pulse generation is investigated in a compact laser system based on YAG:Nd3+ with passive Q-switching, which utilizes segmented pumping of the active medium by seven quasicontinuous laser diodes with fiber-optic radiation outputs. The dependence of lasing on the individual and correlative properties of pumping channels is studied in general and upon disabling one or several pumping channels. The maximum output emission energy achieved is 20 mJ for a synchronous pulse with a duration of 3.3 ns. The possibility of obtaining a stable optical breakdown of air using the developed laser is experimentally confirmed, facilitating its practical application in, for example, the ignition of combustible mixtures.
