Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable.. The technology is useful where the physical connections are impractical. RESTON, Va., Sept. 11, /PRNewswire/ -- Laser Light™ Communications, LLC was launched today at the World Satellite Finance Forum in Paris, Light.
Of all the devices that produce laser light, laser diodes or semiconductor lasers are the most efficient and they come in smaller packages. So they are widely used in various devices like laser printers, barcode readers, security systems, Autonomous vehicles (LIDAR), Fiber optic communications etc. Also read about Light Emitting Diode. Laser communications systems are wireless connections through the atmosphere. They work similarly to fiber optic links, except the beam is transmitted through free space. While the transmitter and receiver must require line-of-sight conditions, they have the benefit of .

Korevaar (). Free space laser communications Abstract: Summary form only given. Increased data transfer demands, limited RF spectral allocations, and emphasis on smaller spacecraft platforms to keep launch costs down are forcing space mission planners to consider free-space optical communications for their space-ground and intersatellite communications links.
receive and to convert at high efficiency, very high intensity laser light of over W/cm 2, presents a unique opportunity for the development of the robust free space optical communication system by modulating information signals onto the transmitted.
Free Space Laser Communications Dr. James Lesh Jet Propulsion Laboratory California Institute of Technology T4 [Outline of Presentation ] • Fundamentals Free Space Propagation • Electromagnetic beams diverge at rates at least as fast as L/d (Diffraction-limit) - _, is the wavelength of the radiation.
The most challenging aspect of free-space lasers in such applications is pointing and locking-on with the beam. Since the angular divergence is just a few micro-radians, this translates to an area of just 1 ftz at a distance of miles. NASA also has an free-space laser experiment planned for the International Space Station (ISS).
Laser communications is almost perfect for use in space. It requires less power, is lighter, and has faster data rates than radio communications. Within 10 years I expect that most, if not all space-to-space communications will be done with lasers.

Laser communications systems work similarly to fiber optic links, except the beam is transmitted through free space. In Laser Communication the transmitter and receiver must require a line-of-sight conditions and Laser communications systems have the benefit of eliminating the need for broadcast rights and buried cables.
Laser communications offer a viable alternative to RF communications for intersatellite links and other applications where high-performance links are necessity.
High data rate, small antenna size, narrow beam divergence, and a narrow field of view. The latest developments in laser based sensing and free space laser communication. Sophisticated laser system concepts are increasingly being used to address high bandwidth free space optical (FSO) communications needs and for sensing applications.

Abstract: To understand the history of free-space laser communications or lasercom one must do so in the context of the development of the technology in general and the different programs and players over the years. It is noted that the term lasercom was actually put under copy write by McDonnell Douglas in the early '80s but has been used extensively in the industry to refer to free-space.
