Outline of Final Research Achievements |
The characteristics of spectral compression using comb profiled fiber were investigated numerically, and improved configuration was obtained, and experimentally demonstrated. The improvement of pedestal suppression ratio from 1 to 8 dB was achieved. Then, a high power, high repetition rate fiber laser using single wall carbon nanotube was developed for power scaling of the narrow linewidth source. The power scaling up to double was achieved using the developed fiber laser. Then, rapid wavelength tuning was demonstrated using an electro-optical modulator. We are planning to develope the fast, and ultrahigh resolution OCT system using the developed light source.
