Laser communication has advances in compared with radio frequencycommunication as result of much high carrier frequency from ultraviolet to nearinfrared. Very narrow laser beam is possible to form with very high powerdensity. But laser beam has high destruction and attenuation on clouds,turbulence, scattering on aerosols and molecules of the atmosphere. Low Earthorbits (LEO), Middling Earth orbits (MEO) and partly Geosynchronous Earth orbit(GSO) satellites moving on the sky and laser light from satellites moves acrossdifferent turbulence conditions of the atmosphere, clouds, molecules of theatmosphere H2O, O2, N2, CO, O3 and other. We performed unique experiments withpropagation of laser beams from beacon of OPALE terminal of ARTEMIS satellitethrough thin clouds. We have found that small part of laser radiation isreceived from ahead point there the satellite will be after time of propagationof laser radiation from the satellite to telescope. It is in accordance withtheory of relativity for aberration of light during transition from moving tonot moving coordinate systems. It is positive effect for laser communicationthrough the atmosphere and clouds because will be possible to develop a systemfor reduce of the atmosphere turbulence during of laser communication fromground to the satellites. The interest is what will be during propagation oflaser radiation from the satellite through strong clouds. The detaildescriptions of laser experiment with ARTEMIS GSO satellite through strongclouds and estimations of the laser power through strong clouds are presentedin this paper. Accordingly we must search the optimal wave lengths and power oflasers for performs laser communication in different cloudy conditions.
