Laser Communication

Laser communication is a technology that uses lasers to transmit information through light signals. This method involves encoding data into a laser beam, which can be modulated to carry the information across various distances. Lasers provide a focused and coherent beam of light, which allows for high-speed data transmission with minimal loss and interference. Laser communication can be utilized in various applications, including satellite communications, deep-space communication, and free-space optical communication between terrestrial points. Because lasers can operate at different wavelengths, they can also support multiple communication channels simultaneously, enhancing data transfer efficiency. Additionally, laser communication systems are often characterized by their ability to establish secure connections, as the tightly focused beams are less susceptible to eavesdropping compared to traditional radio frequency communications.
