The main purpose of the research was to implement the mode of generating ultrashort
picosecond duration pulses using a rapidly relaxing dye and the method of cavity losses
discharge of еру pulsed solid-state lasers with a passive gate. We calculated the genera-
tion kinetics and determined the optimal conditions modulation mode in combination
with passive gate enlightenment. We implemented the method for the YAG: Nd
3+
laser, for
which we obtained the intense ultrashort pulses with duration of ≈12 ps, corresponding
to the maximum width of the emission spectrum of the nonselective resonator.
Keywords:
picosecond laser pulses
,
rapidly relaxing passive gate, Q-switched laser.
