研究概要:Scintillation for a laser beam of 7μm band is described. Power spectral density function (PSDF) of the log-amplitude scintillation was experimentally obtained and an enhancement of the spectral level in the lower frequency were found. Fluctuation for the laser beams of wavelengths on and off an absorption line were recorded, and the PSDF for each record were calculated, and the co-spectrum of the two records as well. Footprints of transportation of the absorbing gas were found in the frequency region less than 10^<-1>Hz in both spectra.
