Abstract(in English) | Dispersion-tuned fiber laser is fast and widely wavelength-swept fiber laser, which is suitable for optical coherence tomography application. In order to extend the imaging depth, the instantaneous linewidth of the laser should be narrowed. The higher modulation frequency for mode-locking leads to narrower linewidth. However, it also bring a narrowing of tuning range, which means the axial resolution of OCT worsens. One method to solve this trade-off is using pulse modulation. By using this modulation scheme, we can achieve effectively high modulation frequency without narrowing the tuning range. In this paper, the difference of the laser performance between sine modulation and pulse modulation is discussed. |
