Single mode EDF fiber laser using an ultra-narrow bandwidth tunable optical filter
Single longitudinal mode (SLM) erbium-doped fiber (EDF) laser operation using a commercialized ultra-narrow bandwidth optical filter has been demonstrated. A 2-m long EDF with an absorption coefficient of 24 dB m-1 at the pump wavelength is used as gain medium. The ultra-narrow tunable filter is use...

| 總結: | Single longitudinal mode (SLM) erbium-doped fiber (EDF) laser operation using a commercialized ultra-narrow bandwidth optical filter has been demonstrated. A 2-m long EDF with an absorption coefficient of 24 dB m-1 at the pump wavelength is used as gain medium. The ultra-narrow tunable filter is used for selection of a single longitudinal mode from the available spectrum of multiple modes, which originally exist in the FBG's reflection spectrum. Our approach provides a relatively simple and direct method for realization of SLM operation. A high-resolution optical spectral analyser with a resolution of 0.16 pm isused to observe the output spectrum. To verify the SLM operation, the delayed self-heterodyne methodis used, giving a measured laser linewidth of 61.5 kHz. |
