Abstract
A UNIQUE BLUE/GREEN HIGH POWERED LASER SYSTEM FOR TACTICAL SUBMARINE COMMUNICATIONS IS PROPOSED. THE PROPOSED SYSTEM COMBINES THE CONCEPTS OF DOUBLE BEAMS MODULATION (DBM) AND OPTOELECTRONI HETERODYNE (OEHD) HAS MANY ADVANTAGES OVER THE CURRENT INCOHERENT OPTICAL SYSTEM (BECAUSE OF THE SPATIAL INCOHERENT CAUSED BY EXTREME TURBIDITY, THE CONVENTIONAL COHERENT DETECTION IS IMPOSSIBLE) PROVIDES THE NEEDS FOR REAL-TIME, WIDEBAND COMMUNICATION BETWEEN SUBMARINE AND SURFACE COMBATANT. IT CAN TRANSMIT VERY HIGH FREQUENCY, WIDE BANDWIDTH, ANALOG, DIGITAL OR VIDEO SIGNAL SIMULTANEOUSLY UP TO TENTH OF A GHZ. IT OFFERS THE ABILITY FOR MULTICHANNEL TRANSMITTING AND SWITCHING. BY ADOPTING THE OEHD, IT NOT ONLY INCREASES THE DETECTION SENSITIVE OVER THE CONVENTIONAL INCOHERENT SYSTEM, BUT ALSO SIMPLIFIES THE DESIGN OF THE RECEIVER. THE SYSTEM CAN BE VERY COMPACT, MECHANICALLY RELIABLE AND LOWPOWER CONSUMPTION BY OPTO-ELECTRONIC INTEGRATING AND DIRECTLY DIODE PUMPING "KTP STAR." A SECOND HARMONIC GENERATOR (SHG) WHICH CONVERTSTHE LASER TO BLUE/GREEN WITH EFFICIENCIES OVER 65%. IN PHASE I, BRIMROSE WILL CONSTRUCT A PROOF-OF-CONCEPT LASER TRANSMITTER-RECEIVER SYSTEM. SHOULD THIS WORK BECOME CLASSIFIED, BRIMROSE HAS A SECRET FACILITY CLEARANCE. ALSO, UNDER THE SBA FROM THE 0FFICE OF INNOVATION RESEARCH AND TECHNOLOGY-S SIXTH YEAR RESULTS TO CONGRESS, JUNE 1989, BRIMROSE WAS SELECTED FROM 9,000 COMPANIES FOR OUTSTANDING SBIR COMMERCIALIZATION PROGRESS AND SUCCESS.
