Paper Abstract

Laser communication offers many advantages in space- and weight-critical applications. Swept volume and weight of the receiver are reduced through use of laser communications, and communications security is enhanced. A critical parameter in the performance of a laser communications system is receiver gain, given by:1 GR = π2 dR_ λ2 (1) where dR is the receiver aperture and X is the receiver operating wavelength. For maximum receiver gain, the receiver aperture should be as large as possible and the wavelength as short as possible. Wavelength is frequently decided by considerations of propagation, interference, and the availability of lasers of the appropriate characteristics. Increased gain therefore requires more receiver aperture. To maintain the advantages of light weight and minimum swept volume, the laser communications receiver must have the lightest possible receiver for a given aperture.
