Abstract

The atmospheric transmittance of high power laser along a ground-space slant path has been comprehensively investigated in this paper, which could be used for performance prediction and parameter estimation in the field of laser engineering. First of all, the atmospheric transmittances along a ground-space slant path are studied with the different launch parameters of high power laser. The center wavelength of laser is a critical element that affects the atmospheric transmittance, while the influences of other parameters can be almost negligible. The atmospheric transmittances of high power laser along a ground-space slant path are secondly researched under the different meteorological conditions. The atmospheric transmittances of high power laser along a ground-space slant path are lastly calculated under the different propagation conditions. The results indicate that atmospheric transmittance through the whole atmosphere decreases as the zenith angle increase; the differences remain in 2 percent when the zenith angle is less than 20 degree for 532nm laser. In the view of propagation length, it is the range below the altitude of 6km that mainly affects the transmittance of high power laser along a ground-space slant path.
