Plasma Dynamics Of A Laser Filamentation-Guided Spark
PHYSICS OF PLASMAS(2016)
摘要
We investigate experimentally the plasma dynamics of a centimeter-scale, laser filamentation-guided spark discharge. Using electrical and optical diagnostics to study monopolar discharges with varying current pulses, we show that plasma decay is dominated by free electron recombination if the current decay time is shorter than the recombination characteristic time. In the opposite case, the plasma electron density closely follows the current evolution. We demonstrate that this criterion holds true in the case of damped alternating current sparks, and that alternative current is the best option to achieve a long plasma lifetime for a given peak current.
