Create an optical link budget for an Alpha-Centauri mission.

Computes a link budget for transmission from an Earth-orbit-based station to a receiver in the Alpha Centauri system. Therefore there are no atmosphere losses. ------------------------------------------------------------------------- References: Lambert, S. G. and W. L. Casey (1995.) Laser Communications in Space.
