Abstract:

The laser submarine communication system is able to send a signal through seawater to a great depth and transmit information at a rapid rate.It is important in the communication with a submerged vessel.The current domestic and foreign research on the laser submarine communication is presented.The research on laser transmitting properties in communication channel is proposed.The necessity of the research on the uplink channel of the submarine communication,especially in seawater-air interface's simulation,is shown.This study shows that communication system with the blue-green laser communication system as the core technology and the very low frequency (VLF) and extremely low frequency (ELF) system as the peripheral technology is the direction of the future laser submarine communication.

Key words: submarine communication;optical communication channel;blue-green laser
