Ranging measurements in the radio band have been extensively used in space-based applications, for example in GNSS for navigation and GRACE for mapping the Earth-s gravity field. However, the increasing demand for high-bandwidth communication and precision ranging will make optical systems ideal for these applications. Our investigations are focused on inter-spacecraft laser ranging and data communication...
The authors presented the corresponding measurements obtained with a modified version of our heterodyne interferometer. The measurement were obtained in the 6s 2S1/2 F=4 rarr 6p 2P3/2 F=5 transition of the caesium D2 line. As it is the case for double linear polarisation the probe absorption signals showed electromagnetically induced absorption. However, the amplitude of the induced absorption peak...
