Abstract
We present a wavelength selectable actively mode-locked ring fiber laser. We used for the reflection sampled fiber Bragg gratings (SFBG) with 25GHz spacing and high harmonic mode-locking frequency modulation. The method includes successive SFBGs mirrors with different reflecting wavelengths, each SFBG determines a different cavity length and therefore a different modulation frequency. The selection of the wavelengths is performed by applying the corresponding frequency.
