| Outline of Final Research Achievements |
First, we developed highly stable optical frequency comb source using nonlinear polarization rotation type ultrashort pulse fiber laser, and octave spanning, coherent supercontinuum comb source. Next, we investigated quasi-dispersion increasing comb profiled fiber. Using the developed comb profile fibers, we demonstrated the narrow linewidth, wavelength tunable comb source. We also developed novel single wall carbon nanotube polyimide film working at 2.0 um wavelength range. Using the developed nanotube film device, an all-fiber type, high power, ultrashort pulse Tm doped fiber laser was developed.
At 1.55 um wavelength range, we demonstrated all-polarization maintaining type, bi-directional dual comb fiber. Then we succeeded in the fundamental experiment of wideband dual comb spectroscopy. Finally, we developed environmentally stable, all-polarization maintaining, figure 9 fiber laser. The dynamics inside the laser and the initial process of passive mode-locking were clarified.
