UNDER THE PHASE I (CONTRACT # NNL04AB38P) OF THIS PROGRAM, MONOLITHIC MICRO-LASER WITH KTP RIDGE WAVEGUIDES FOR INJECTION SEEDING HIGH POWER LASERS, ADVR, INC. DEMONSTRATED HIGH EFFICIENCY POTASSIUM TITANYL PHOSPHATE (KTP) WAVEGUIDE FREQUENCY DOUBLER FOR CONVERTING 1064 NM LASER LIGHT INTO 532 NM LASER LIGHT. PRELIMINARY TESTS WERE ALSO PERFORMED ON KTP PHASE MODULATORS AND WAVEGUIDE SPLITTERS. UNDER PHASE II (CONTRACT # NNL05AA12C) OF THIS PROGRAM, COMPACT, LOW-COST, FREQUENCY-LOCKED SEMICONDUCTOR LASER FOR INJECTION SEEDING HIGH POWER LASER SYSTEMS , A COMPACT, ROBUST AND HIGH-EFFICIENCY FIBER-COUPLED KTP WAVEGUIDE WAS FABRICATED AND INCORPORATED WITH A SINGLE FREQUENCY FIBER LASER, A FIBER AMPLIFIER, A PHASE MODULATOR, A MINIATURE IODINE CELL AND OTHER FIBER OPTIC COMPONENTS IN A COMPACT PACKAGE TO SERVE AS A SEED LASER FOR LIDAR APPLICATIONS. THE PROPOSED PHASE III SBIR INVOLVES DEVELOPING KTP WAVEGUIDE FREQUENCY DOUBLER AND A KTP WAVEGUIDE FREQUENCY TRIPLER INTO A SINGLE COMPACT, ROBUST AND HIGH EFFICIENCY FIBER-COUPLED PACKAGE. THIS APPLICATION REQUIRES THE MELDING OF PRIOR SBIR PHASE II WAVEGUIDE DOUBLER TECHNOLOGY WITH NEWER WAVEGUIDE FREQUENCY TRIPLING TECHNOLOGY INTO A SINGLE COMPACT FIBER COUPLED PACKAGE TO PRODUCE TUNABLE CW ULTRAVIOLET LIGHT. WE BELIEVE THAT THE SUCCESSFUL DEMONSTRATION OF THIS APPLICATION WILL LEAD TO THE DEVELOPMENT OF A NEW PRODUCT THAT WILL BE OF INTEREST TO BOTH NASA AND COMMERCIAL CUSTOMERS OF LIDAR SYSTEMS. IN FACT SUCH A PRODUCT WILL BE CRITICAL AS A SUBCOMPONENT IN THE NASA LANGLEY INSTRUMENT INCUBATOR PROGRAM TECHNOLOGY DEVELOPMENT FOR A COMBINED HIGH SPECTRAL RESOLUTION AND OZONE DIFFERENTIAL ABSORPTION LIDAR.
