IGF::OT::IGF CO2 SENSING USING ABSORPTION BANDS NEAR 1570NM IS VERY ATTRACTIVE BY TAKING ADVANTAGE OF THE MATURE FIBER-AMPLIFIER TECHNOLOGY DERIVED FROM FIBER-OPTIC TELECOM HERITAGE. THIS NECESSITATES SUFFICIENT POWER SCALING IN 1.5 MICROMETER FIBER-AMPLIFIERS, EITHER IN THE PULSED-MODE, OR IN THE CW-MODE FOR MODULATION SPECTROSCOPY.IN THIS SBIR PROGRAM WE PROPOSE THE DESIGN, OPTIMIZATION, EXPERIMENTAL EVALUATION AND PROTOTYPE DEVELOPMENT OF A HIGH-POWER,HIGH WALL-PLUG EFFICIENCY, 1571.1 NM FIBER-AMPLIFIER LASER TRANSMITTER, COMPATIBLE WITH MULTI-LINE CW INTENSITY-MODULATED INTEGRATED-PATH DIFFERENTIAL ABSORPTION SPECTROSCOPY, WITH THE SIZE, WEIGHT AND POWER (SWAP) OPTIMIZED FOR AIRBORNE AND EVENTUAL SPACEQUALIFIABLE ROADMAP FOR ASCENDS MISSION. WE LEVERAGE INNOVATIONS IN HIGH-POWER 1.5 MICROMETER FIBER-OPTIC TECHNOLOGY AND FIBER-AMPLIFIER ARCHITECTURE, WHILE USING HIGH-RELIABILITY 1.5 MICROMETER SILICA-FIBER BASED PASSIVE/ACTIVE COMPONENTS. OUR EXPECTATION IS THAT AT THE END OF PHASE 2, A TRL-6 LEVEL HARDWARE CAN BE DEVELOPED AND DELIVERED FOR AN AIRBORNE MISSION, AND WHICH IS ALSO COMPATIBLE WITH A SPACE-FLIGHT MATURATION ROADMAP.
