Abstract

Even in the case of variations in the pulse repetition frequency, a solid-state laser generates laser pulses with constant beam characteristics in such a way that when the pulse repetition frequency of the laser pulses is varied the pulse duty factor of the pumping radiation is kept constant and Q switching is triggered in each case at a prescribed period after the start of the pumping pulse.
