Laser communication applications

Lasers in Communications

• Laser light is used in optical fiber communications to send information over large distances with low loss.
• Laser light is used in underwater communication networks.
• Lasers are used in space communication, radars and satellites.

What are the applications of laser communication system?

Today, diode lasers are the key components of any broadband communication systems. They are employed as high speed transmitter in digital and analog fiber optic networks, to pump lasers in Erbium doped amplifiers (EDFAs), or as high-power pulsed lasers in test and measurement field.

What is an example of a laser application?

Lasers are involved in almost all aspects of these fields, from “light shows” to Compact Discs (CDs) and Digital Video Discs (DVDs), to special effects in the movies. Some other commonplace application of lasers are as Laser pointers, barcode scanners, laser printers, etc.
