Abstract: | We report an experimental demonstration of muliwavelength erbium-doped fiber laser with adjustable wavelength number based
on a power-symmetric nonlinear optical loop mirror (NOLM) in a linear cavity. The intensity-dependent loss (IDL) induced by
the NOLM is used to suppress the mode competition and realize the stable multiwavelength oscillation. The controlling of the
wavelength number is achieved by adjusting the strength of IDL, which is dependent on the pump power. As the pump power increases
from 40 to 408 mW, 1–7 lasing line(s) at fixed wavelength around 1601 nm are obtained. The output power stability is also
investigated. The most power fluctuation of single wavelength is less than 0.9 dB, when the wavelength number is increased
from 1–7. |
