激光等离子体引导空气间隙放电的实验研究
Experiment Study on Discharge Characteristics of Air Gap Guided by Laser Plasma
摘要
Abstract
In order to promote the practical application of laser induced lightning technology,in this paper we performed the experiment study on discharge characteristics of air gap guided by laser plasma.A solid Nd:YAG nanosecond pulse laser is used to ionize the air,produce plasma channel and then induce the breakdown of air gap between electrodes with applied high voltage.The experiment platform and measurement system was built.The discharge experiment,guided by different laser power (200、400 m J) and laser wavelength (532、1 064 nm),was developed.The effect of laser plasma parameters on the breakdown characteristics of air gap was obtained.The results show that the breakdown threshold voltages at different gap distances decrease with the laser power output and then saturate to a voltage value.At the same laser power output,the breakdown threshold voltage with 532 nm laser is lower.The results provide experimental support for the development and application of laser guided lightning.关键词
