Application developments are in an early phase for the space transmission of laser energy. The recent development of drone systems has been remarkable, and a power beaming system for drones is a promising technology. The atmospheric phenomena, which inhibit the optical energy transmission, are thermal blooming and atmospheric turbulence. In this article, we describe the influence of these phenomena on the transmitted wavefront of the laser beam and our research progress on wavefront control.
