摘要: Abstract A suppressant effect of wavelength competition for multi-wavelength lasing oscillations is experimentally demonstrated in an ordinary erbium-doped fiber laser (EDFL). The polarization hole burning exploited by a segment (EDF) coiled round the plates three-loop controller. mechanism to suppress discussed detail. Results show that helpful obtain stable at room temperature EDFL. By properly adjusting comb filter, three-wavelength and tunable dual-wavelength have been achieved. power fluctuation measured be less than 0.75 dB over 30 min all obtained experiment. 3 dB bandwidth each oscillation 0.01 nm 30 dB 0.10 nm. side mode suppression ratio (SMSR) more 45 dB 50 dB.
