A dual wavelength high power double-clad erbium/ytterbium-doped fiber laser with a narrowest spacing of 0.4 nm and a M2 value of close to unity is presented in the region of 1565 nm. This result can be realized with a significant improvement of the mode competition problem using a loop mirror as a comb filter. The wavelength region can also be varied using polarization controllers in the loop mirror. This dual-wavelength fiber laser with side mode suppression ratio (SMSR) of 40 dB is quite stable, and the output power variance is as low as 0.46 dB.

This paper demonstrates a multiwavelength fiber laser (MWFL) with erbiumdoped fiber amplifier (EDFA) as gain  medium and Sagnac loop mirror interferometer as filter. Stable and flat lasing spectrum was achieved when highly  nonlinear fiber (HNLF) was inserted into the laser cavity. The number of lasing lines and extinction ratio (ER) was directly influenced by EDFA gain where at maximum setting, 14 lasing lines with ER of 19 dB were generated. The  stable and flat spectrum achieved spanned about 1.6 nm. This is due to the induced intensity dependent loss  mechanism in the cavity by adjusting the half-wave plate of the polarization controller in combination with the  HNLF. The MWFL output showed peak power variation of about 2.1 dB within 100 minutes of observation time.
