Abstract :
The importance of simulated far-field testing of laser intersatellite communication systems is demonstrated through experience gained with and tests performed on a prototype system. It is shown that the performance of the link can be seriously degraded if the magnitude and dynamics of the speckle in the projected far field are not limited or controlled in some manner. System performance is controlled by screening of laser diode/fiber assemblies. Other potential techniques to minimize the impact of speckle are addressed
