Characteristic Study On Ionized Atmosphere With Intence Laser

According to the study on ionized atmosphere with the intence laser.And deals with the ionized atmosphere muti-process caused by the large power laser, and the important roles played by multiphoton ionization and cascade ionization in the w hole ionization process as well as the laser thresholds required by the atmosphere ionization.This article elaborate about the ionization mechanism of ionized atmosphere and the plasma channe that the atmosphere produced, has calculated the laser ionization atmosphere laser threshold, and has weakly the laser threshold intensity which needed to the plasma channel, and has conducted the research to the laser atmosphere ionization effect and its the basic performance.Designed and builded a set from the experiment to be possible to use in the laser ion electrode analog calculator.Useing this set to study the ionized atmosphere By theory union experiment method.Test the intence of ionization and electric conduction ability.Study the relations of the ionized atmosphere with wavelength, power density of laser and the response time.It gives relations of the ionized atmosphere mechanism and laser system parameter.
