Abstract： |
The present invention belongs to the field of optical fiber laser technology, and features that the full optical fiber multi-wavelength Raman laser with flat broadband envelope consists of high nonlinearity Raman gain fiber, two wideband WDM couplers connected on two sides of the Raman gain fiber separately, zero-dispersion high nonlinearity fiber, comb filter, wideband fiber loop reflectors on two ends and fibers to constitute laser transmission channel. The full optical fiber multi-wavelength Raman laser may have increased optical coupler and wideband fiber coupler to constitute single-way circulating fiber ring cavity. Compared with conventional optical fiber multi-wavelength Raman laser, the present invention has the advantages of utilizing pump source with small wavelength number in obtaining flat broadband envelope and flexible waveband design of the output laser spectrum. |
