dcterms.abstract | The embodiment of the invention provides a Fourier mode-locked laser. The Fourier mode-locked laser comprises a sweep frequency filtering unit, an optical amplification unit, a first optical beam split unit, a first optical isolation unit, a light delay unit, a polarization control unit and an intensity modulation unit which form an optical loop by a fiber. The embodiment of the invention providesa time domain modulation technology-based Fourier mode-locked laser comprising the sweep frequency filtering unit, the optical amplification unit, the first optical beam split unit, the first opticalisolation unit, the light delay unit, the polarization control unit and the intensity modulation unit which form the optical loop by the fiber, a high-quality short-pulse optical signal can be generated, so that the pulse width and the modulation speed of the pulse optical signal can be freely adjusted by controlling a driving signal, the Fourier mode-locked laser is high in flexibility and rapidin response speed, the high-frequency fluctuation noise can be effectively suppressed, the signal quality is improved, and the coherent length and the signal-to-noise ratio of the optical signal areimproved. | - |
