Abstract

We investigate discrete wavelength tuning characteristics of a single-frequency fiber laser locked to either of two external lights. Frequency locking is achieved by the cooperatively induced spatial-hole burning (SHB) of a saturable absorber in the laser cavity. We show that lasing frequency is well locked to either of the two external lights when the lasing wavelength of the fiber laser is adjusted to the corresponding wavelength of the external light by tuning the bandpass filter in the laser cavity. The locked frequency stability of the fiber laser is as high as that of the employed external light source.
