Laser communications

One of the driving forces behind the advancement of laser diode technology is optical communication. Similar to fibre optic systems, these wireless connections across the air use laser diodes to produce the signal carriers that are used as transmission mediums. As a transmission medium, light is used in optical communication.

Free space communications and sensing using lasers are helping to improve detection methods. For satellite communication, laser is used, which has the ability to transfer a lot more data than radio.
