The pulse Nd:YAG laser whose wavelength is 1.06 μm and the single pulse energy is about 500 mJ is focused by a lens with 300 mm focal length. So the laser energy density leaps at the focus and it leads to atom ionization phenomena. At the phenomenon of laser scattering with the same wavelength and multi-spectral electromagnetic radiation, the distributions of spacial spectrums are detected. And the spacial distribution states of pulse laser with 1.06 μm scattered by plasma in the atmosphere are obtained. The scattering states are measured and analyzed by HR4000 spectrometer. According to the simulation calculation of a computer, the directional pictures of the laser with 1.06 μm wavelength from plasmas scattering are obtained. Based on Mie theory, the relationship between the scattering angle and scattering intensity of the pulse laser with 1.06 μm incident wavelength is explained.
