Abstract

In order to study the evolution of laser-induced plasma and obtain the properties of plasma, transversely excited atmospheric CO2 laser was focused by a parabolic reflector to generate air breakdown plasma. Based on the imaging spectrometer system and intensified CCD detector, time-space resolution of laser-induced air plasma were investigated and the time evolution spectra and the space resolution spectra of plasma were obtained. Electron temperature of about 4104K and electron density of 1018cm-3 were calculated respectively by using the ratio of oxygen line spectrum and continuous spectrum and full width at half maximum of spectral line. The results show high-energy laser-induced plasma spectra radiate the intense continuous spectra outward, comparing with low-energy laser-induced plasma spectra. At the same time, laser-induced air plasma expands outward rapidly with the way of the laser-supported detonation wave. Due to the shielding effect of laser power, laser-induced air plasma shows the behavior of spatial separation. The results are useful for understanding the interaction between plasma and high-energy laser.
