Modulation Method of Laser for Underwater Communication
Keywords: Blue green lasers, Laser applications, Sonar technology, Underwater communication system, Pulse interval modulation
AbstractDue to very high absorption of light in the water it is necessary to use high energy pulsed bluegreen lasers for underwater communication systems. However,these lasers do not have high repetition rates, sufficient enough to support high data rate signals. The pulse interval modulation method is one of the prospective methods of sending large bandwidth data using low frequency (500 to1000 pulses per second) pulsed laser. This method appears to be more promising for underwater communication system with likely development of fast PIM coder/decoder.
