50% flashover voltage characteristics and the discharge development of positive discharges guided by CO₂ lasers have been experimentally studied up to a 7 m air gap. In these experiments, we found that plasmas can guide and trigger the positive discharges under certain conditions. The applied voltage is the condition of the guide effect by laser-produced plasmas and the number of the laser-produced plasmas is the condition of trigger effect by the plasmas. On the basis of these results, we explain the mechanisms of the laser-guided positive discharges. In these mechanisms, a continuous plasma channel which is produced by the expansion of discrete plasmas play important roles. Such characteristics of the laser-guided positive discharge suggest that we must produce a continuous plasma channel at the top of the tower for laser-triggered lightning.
