Abstract
A dual wavelength optical fiber laser includes a first and a second optical fibers which generating stimulated scattering by a pump light source; two short period optical fiber gratings that is resonating each of a first and a second wavelength light which are generated by the optical fibers and regulating reflecting characteristics according to the first and the second wavelengths; a WDM optical fiber coupler which inputs a pump wavelength to the optical fibers and outputs a laser operation wavelength; and an interference removing unit which is connected between the optical fibers and removes an interference in the first and the second wavelength of resonating.
