Synchronization in laser triggered transformer-type high power pulse modulator
摘要
Abstract
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, which is also the gas breakdown voltage, the high power electrical pulse with voltage of -305 kV, current of 20 kA and pulse width of 126 ns is obtained at the dummy load. The delay between the time that the laser pulse arrives at the switch and the switch breakdown moment is 35 ns.关键词
