| 摘 要： | We propose and demonstrate a new concept of stable narrow-line-width and close wavelength spacing dualwavelength lasing in an Er-doped fibre ring laser （EDFRL） by cleaving the spectrum with a wavelength-selective component in the EDFRL. A fibre loop mirror （FLM） combining with a polarization controller （PC） acts as the cleaver. The cleaver can produce a fine pectinate spectrum. By adjusting the PC, the fine pectinate spectrum can be so changeable that cleaving the spectrum of a fibre Bragg grating （FBG） into two parts. As a result, we obtain the dual-wavelength fibre lasering with a bandwidth of only 0.03nm and a wavelength spacing of only 0.07nm. Furthermore, the laser can also perform stable switchable single wavelength or stable different-bandwidth dual-wavelength by carefully adjusting the PC at room temperature. |
