Abstract
With the phase screen theory, distribution of light field on the take-over plane is analyzed and simulated after a Gaussian laser beam propagates in the turbulent atmosphere. The square difference of light intensity scintillation is given out, and compared with a static state statistical quantity theoretically. Analogously, thermal blooming effect is introduced and simulated after a beam of high-power Gaussian laser spreads in atmosphere. A technique was proposed that the empirical formula of thermal blooming was employed with a modification by turbulence effect. The combined effects are introduced and simulated while a high-power laser beam propagates in atmosphere.
