Public award description
MODERN WATER VAPOR DIFFERENTIAL ABSORPTION LIDAR (WV-DIAL) USES A SINGLE FREQUENCY DISTRIBUTED BRAGG REFLECTOR (DBR) LASER DIODE TO SEED A PULSED SEMICONDUCTOR AMPLIFIER. TO MEET THE DEMAND OF THESE ADVANCED INSTRUMENTS, THE DEVELOPMENT OF DBR LASERS AT MULTIPLE WAVELENGTHS IN THE 700-950NM REGION IS REQUIRED. CURRENT DIAL SYSTEMS USE FREE-SPACE LASERS THAT REQUIRE BULK OPTICS AND ARE SUBJECT TO MISALIGNMENT AND CONTAMINATION. A COMPACT INTEGRATED LASER MODULE IS DESIRABLE FOR FUTURE COST-EFFECTIVE, RUGGED AND FIELDABLE SYSTEMS. BUILD ON THE DESIGN AND PROTOTYPE DEMONSTRATION OF PHASE I, WE PROPOSE TO FURTHER THE DEVELOPMENT OF THE COMPACT INTEGRATED LASER MODULES. OUR APPROACH, WITH THE FABRICATION OF HIGH PRECISION DBR LASER OF 935NM AND 817NM WAVELENGTHS; AND THE PACKAGE ENGINEERING OF COMPACT INTEGRATION, WILL PROVIDE THE NARROW LINEWIDTH AND HIGH POWER LASER MODULES FOR NUMEROUS LIDAR APPLICATIONS WITH THE ADVANTAGES OF REDUCED SIZE, WEIGHT AND POWER (SWAP).
