Future interplanetary missions, including robotic probes and human travel, will require significantly enhanced communications bandwidth that will be difficult to realize with current radio/microwave frequency links. Besides satisfying this requirement, optical (laser) communications has the potential for substantially lowering mass, power, and volume burden on the host spacecraft; is free from spectrum allocation issues; and can potentially support tracking functions resulting in improved spacecraft navigation. Primary challenges of optical communications include precision laser beam pointing over the huge planetary range, inefficiency of laser transmitters, quantum noise limited detection, especially in presence of additive background during periods of near Sun pointing, atmospheric degradation due to attenuation and turbulence and weather outages. This paper will briefly review the status of technologies that have been devised to meet these challenges and system-level developments for bi-directional telecommunications and ranging to distant probes.

Highly efficient and high output power of erbium doped fiber laser in a linear cavity configuration

et al. 2010

View full text Add to dashboard Cite

A simple Erbium Doped Fiber Laser (EDFL) in linear cavity configuration is reported. The cavity design is based on an FBG as a back reflector, and a loop back optical circulator with an output coupler as the front reflector. Different coupling ratios of the coupler are tested and 50: 50 provides the highest coupling output power of 22.06 dBm (160.7 mW). The pump power conversion efficiency is about 95% when pumping with two

Lidar systems have played an important role in space rendezvous and docking (RVD). A new type of scanning lidar is developed using a high-repetition-rate pulsed fiber laser and a position detector. It will be a candidate for autonomous space RVD between two spacecrafts. The lidar can search and track cooperative targets in a large region without artificial guidance. The lidar's operational range spans from 18 m to 20 km, and the relative angle between two aircrafts can be measured with high accuracy. A novel fiber laser with tunable pulse energy and repetition rate is developed to meet the wide dynamic detection range of the lidar. This paper presents the lidar system's composition, performance, and experimental results in detail.
