METHOD OF INCREASING RANGE OF HIGH-SPEED OPEN OPTICAL LINKS WITH UNDERWATER FACILITIES

摘要

FIELD: physics.SUBSTANCE: method employs a laser beam consisting of pulses with duration of not less than 1 ns, which are generated from a plurality of waves by phase synchronisation and interference. Laser pulses with duration of 1 ns or less are generated by synchronising mode components and coherent interaction thereof on a propagation path. Pulse-periodic optical pulses are generated from the plurality of continuous mode components, wherein the repetition of said pulses is determined by the spectral composition of the laser radiation. The pulse sequence is detected by a photodetector as presence (or absence) at given moments in time of a radiation pulse by chirping the spectral frequency of the laser radiation. A binary code is generated to transmit information.EFFECT: longer range of optical communication owing to improved transmission of signals through attenuating portions of a path.4 dwg
