Abstract： |
The invention relates to a multiwavelength simultaneously-exciting erbium-doped optical fiber laser working in green house, composing an annular optical cavity by an erbium-doped optical-fiber amplifier, an output coupler and a comb filter, and its characteristic: at least an high-nonlinear optical fiber segment is inserted in the annular optical cavity. Its structure synthetically uses the advantages of high gain and high pumping converting efficiency of erbium-doped optical fiber and the character of energy diffusion from high-power wavelength to low-power wavelength in high-nonlinear optical fiber, caused by parameter four-wave frequency mixing, to effectively prohibit uniform widening characteristic of the erbium-doped optical fiber and realize simultaneous excitation of multiwavelength in the green house. |
