This chapter discusses the fundamental physics of space optical propagation applicable to integrated space/aerial, terrestrial, and underwater communication links. Slant-path free-space optical (FSO) communication links between an optical ground station (OGS) and the satellite at various orbits and altitudes include GEO, LEO, HAP, and small or even microsatellites, which are analyzed with appropriate accepted optical channel models and atmospheric propagation parameters. Various FSO transmitting beam shapes to optimize long-distance data transmission are discussed. FSO communication technologies for 5G networks and future 6G evolution are explained. Underwater free-space optical (uFSO) communications for POTENTIAL Global connectivity at Gbit/s data rate is presented.
