Outline of Final Research Achievements

In this project, we investigated the development of highly functional optical frequency comb source using high power ultrashort pulse fiber laser with carbon nanotube. First, the improvement of nanotube fiber laser was investigated, and a high-repetition rate, high power fiber laser was developed. Next, a similariton fiber amplifier was developed to generate high power ultrashort pulse with ideal shape, and an octave spanning coherent SC was generated. Then, a high performance optical frequency comb system was developed, and the stabilization and compression of fceo spectrum was realized. Finally, the output pulse from optical frequency comb was amplified and then introduced into highly nonlinear fiber, and wideband, coherent SC comb was realized.
