In calculations we have used the extended Huygens-Fresnel integral and variation of the rate of dissipation of turbulent kinetic energy of Persian Gulf. The turbulence effects on beam spreading and the aperture and lens effects on spot size and the detector’s received power are calculated. The results may be useful for underwater optical communication systems. M3 ER -
