Overview of deep space laser communication
Science China Information Sciences, 2017The deep space probe is a vital technology for observing andexploring the universe. It is thus intensifying as an aerospace researchfocus on an international scale. Despite improving the frequency band,the conventional microwave communication technique has difficultysatisfying the increased demand for the enormous volume of scientific datareturning to ...

Superdiffraction emitting in space laser communication
SPIE Proceedings, 2006Superdiffraction emitting, i.e. far-field spot compression without energy loss in main lob, in space laser communication can increase the main lob energy density. A smaller far-field spot in conjunction with a higher main lob energy density can improve the detection accuracy greatly, and enhance the communication capability of space laser communication

Limitations on lasers for deep space communication
IEEE Transactions on Communication and Electronics, 1963Because of the increased efficiency made possible by narrower beam widths at visible-light frequencies, laser communication systems have certain advantages over conventional radio systems. However, unless elaborate and costly precision tracking gear is used, extremely narrow beam widths prohibit high reliability of reception.
