When modulator or pumping current for laser is lost, output voltage of pulse transformer T1 will rise to limit set by zener D12, which then conducts lo make Q2 and Q3 absorb current not required by energy storage capacitors.-S.J. Grabowski Pulse Power Supply Design for Laser Pumping Electronics,36:51,p33-35.
