Abstract
Penta-wavelength ytterbium doped-fiber laser had been successfully generated by usingspatial mode beating method at room temperature. A G652D premium fiber patch cable was inserted inside the polarization controller (PC) and connected to an ytterbium-doped fiber ring cavity. By increasing the pump power, stable multi-wavelength with side-mode suppression ratio (SMSR) from 25 dB to 40 dB were obtained from dual-wavelength and up to penta-wavelengths respectively. The uniform wavelength interval spacing was 0.67 nm whereas peak power fluctuation and wavelength shifts were 0.6 dBm and 0.01 nm, respectively for all sets of multi-wavelength. These simple, easy and reliable system offer a stable multi-wavelength generation in a 1-micrometer waveband. © 2021 Institute of Physics Publishing. All rights reserved.
