| titleOfInvention | A kind of Wavelength stabilized erbium doped fiber laser |
| abstract | It the utility model is related to a kind of Wavelength stabilized erbium doped fiber laser, it is characterised in that pumping source, wavelength division multiplexer, Er-doped fiber, isolator, three-dB coupler, Polarization Controller including 980nm, polarization maintaining optical fibre, 90: 10 couplers, spectrometer and the single-mode fiber of two different lengths；By the polarization maintaining optical fibre rotating shaft welding of two described different lengths, the angle of rotating shaft welding is 45 °, and the length difference of polarization maintaining optical fibre is 0.2m；The light that 980nm pumping source is sent arrives Er-doped fiber by wavelength division multiplexer, is connected to isolator, accesses three-dB coupler, then accesses 90: 10 couplers, returns to wavelength division multiplexer, the resonator of whole closing structure composition erbium doped fiber laser.The double-smoothing of Sagnac interference rings effectively inhibits the mode competition of erbium doped fiber laser, the wavelength output stablized.The utility model is directed to the problem of existing fiber laser output wavelength is unstable, it is proposed that a kind of simple in construction, cost is low, the erbium doped fiber laser of stable output wavelength. |
