Results are described of recent contributions to the problem of laser atmospheric scintillation in space laser communication in this paper. The effects of laser atmospheric scintillation on the space laser communication are presented. The reduction in scintillation with different number of transmit apertures, different distance between two transmit apertures and different size of receive aperture is introduced. The method of using adaptive optics to reduce intensity scintillation is also given. A way to solve the problem of laser atmospheric scintillation in space laser communication is introduced at last.
