Abstract

The breakdown characteristics of a short-distance discharge gap in an atmosphere by TEA- CO₂ laser have been studied to control the lightning artificially. It is efficient to enhance the probability of electrical breakdown induced if the focal point is set behind the discharge gap axis or near the negative high-voltage electrode. The length of the optical-breakdown plasma channel is elongated by using the micro-particles diffused in an atmosphere. Using 3 micrometers -diam. aluminum particles, the optical-breakdown threshold is lowered to 15 MW/cm² compared to 0.5 GW/cm² in the absence of the micro-particles.
