Synchronization in laser triggered transformer-type high power pulse modulator

A synchronization system for laser triggered transformer-type coaxial spiral pulse modulator was designed. Using the electrical pulse to trigger the primary trigger switch and the laser pulse to trigger the main gas switch of the pulse forming line (PFL), the PFL is successfully triggered by controlling the working time of both the pulses. The delay and jitter of the electrical pulse generator, pulse transformer, pulse voltage at the load, laser flash-lamp and Q-switch signal were measured and analyzed. The charging voltage of the PFL was sampled after being filtered for avoiding the electromagnetic interference and then introduced to the comparison device to generate transistor-transistor logic pulse to trigger the Q-switch of Nd:YAG pulse laser device. When the PFL is charged at -590 kV
