Free Space Laser Communications

Lasers have been considered for space communications since their realization in 1960. However, it was soon recognized that, although the laser had potential for the transfer of data at extremely high rates, specific advancements were needed in component performance and systems engineering, particularly for space-qualified hardware. Advances in system architecture, data formatting, and component technology over the past three decades have made laser communications in ....etc

Laser communications offer a viable alternative to RF communications for inter satellite links and other applications where high-performance links are a necessity. High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communications that offer a number of potential advantages for system design.

Consider a saturable absorber located at the end of a laser cavity whose transmission function is given by:
T=exp (-a*d)
where d is the thickness of the saturable absorber, and a is the absorption coefficient given by:
a=a0/(1+(I/Isat))
where Isat is the saturation intensity.
Generate a starting optical pulse within the laser cavity to represent photon noise within the cavity by using a random number generator i ....etc
