Schematic of experiment setup.
Oscilloscope trace of switched current from the PCSS triggered by a laser pulse of 8.1 mJ under a bias voltage of 10 kV.
Schematic diagram of the current filament and the distributions of carriers, potential and electric field in the current filaments.
Oscilloscope traces of switched current from the PCSS triggered by a laser pulse of 8.1 mJ under bias voltages of 10, 12.5, 15, 17.5, 20.2 kV. In (b), their peak values of rising edge and the amplitudes of output current respectively.
The influence of the voltage on the characteristics of anode region and the resistance characteristics of anode region, plasma region and cathode region on the lock-on and overshoot state. In (b), the red dashed line shows resistance characteristics on overshoot state, the solid line shows that on lock-on state.
Voltage transient characteristics of PCSS under bias voltages of 10, 12.5, 15, 17.5, 20.2 kV and the turn-off voltage curve.
