How does laser communication system work?

Laser communications systems are wireless connections through the atmosphere. They work similarly to fiber optic links, except the beam is transmitted through free space. The carrier used for the transmission signal is typically generated by a laser diode.

What is the use of laser in communication?

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 an electronic communication system means and what are its three basic units?

The basic components of electronic communications system are the transmitter, communications channel or medium, receiver, and noise. Analog signals (such human voice) or digital signals (binary data) are inputted to the system, processed in the electronic circuits for transmission, and then decoded by the receiver.
