IGF::OT::IGF LISA AND GRACE II, JOINT NASA/ESA MISSIONS, NEED LOW NOISE 1064 NM LASERS FOR PRECISE POSITIONING AND DISPLACEMENT MEASUREMENTS OF SEVERAL SPACECRAFT WITH ~ 10 NM SPECIAL RESOLUTION. USE OF 1064 NM EMISSION WAVELENGTH IS NECESSARY TO ENABLE A FACTOR OF ~2 IN SENSITIVITY IMPROVEMENT, COMPARED TO 1550 NM. IN OUR SBIR PHASE 1 AND PHASE 2 CONTRACTS, WE WERE FUNDED TO CONVERT THE OPERATING WAVELENGTH OF OUR PRODUCT, THE LOW-NOISE PLANEX SEMICONDUCTOR LASER, FROM 1550 NM TO 1064 NM. DURING PHASE II WE DESIGNED, BUILT AND SUCCESSFULLY DEMONSTRATED FIRST IN THE WORLD SEMICONDUCTOR EXTERNAL CAVITY 1064 NM PLANEX LASER WITH LINEWIDTH<5 KHZ AND OUTPUT POWER>20 MW. (THIS HAS RESULTED IN A NEW PRODUCT FOR OUR COMPANY, WHICH HAS ALREADY ATTRACTED CUSTOMERS.) NASA GODDARD TEAM TESTED PROTOTYPES OF THE LASERS AND CONCLUDED THAT, WHILE CURRENT PERFORMANCE IS MEETING THE PERFORMANCE TARGETS OUTLINED IN THE PHASE II PROPOSAL, ADDITIONAL IMPROVEMENTS OF THE PERFORMANCE AND RELIABILITY VERIFICATIONS ARE NECESSARY FOR LISA AND GRACE-II, WHERE ULTRA-HIGH SENSITIVITY OF THE LIDAR BASED INTERFEROMETRIC SYSTEM IS CRITICAL. THIS PROPOSED PHASE IIE STATEMENT OF WORK OUTLINES THE STEPS NECESSARY TO LOWER THE PRESENT PHASE NOISE OF THE 1064 NM PLANEX TO ACCEPTABLE LEVELS FOR THE NASA MISSIONS LISA AND GRACE II. WE ALSO EXPECT THIS PROPOSED IMPROVEMENT WILL RESULT IN NEW CUSTOMERS IN THE GROUND-BASED PRECISION MEASUREMENT COMMUNITY, INCLUDING THE GRAVITATIONAL WAVE DETECTOR NETWORK OF LIGO, VIRGO, KAGRA, AND GEO.
