激光电离空气的研究在各个领域具有重要的意义, 其电离过程是一个包括多光子电离和串级电离两个过程在内的多元过程。通过实验研究发现, 当Nimma-600激光器的驱动电压为880 V, 等离子体区域的面积在激光脉冲产生后约20 ns时达到最大, 等离子体从产生到消逝得持续时间大约为16 μs。

The research on atmosphere ionized by laser is significant in many areas. The ionization is a multi-process which contains multi-photon ionization and cascade ionization processes. Experimental results show that when the drive voltage of the Nimma-600 laser is 880 V, the area of the plasma reaches to the biggest area after the laser pulse generated about 20 ns, and the last time of the plasma is about 16 μs.
