摘要：

We study a mechanism to attain stable and ultra-flat multiwavelength oscillations in erbium-doped fiber lasers (EDFLs). The key concept is to introduce intensity-dependent loss (IDL) into the laser cavity, which can effectively suppress the mode competition in the homogeneously broadened gain medium and ensure a uniform power distribution over wavelengths via the gain-clamping effect. The technique was successfully demonstrated by employing a nonlinear optical loop mirror (NOLM) in erbium-doped fiber laser cavity. Based on the experimental results, further experimental investigation and theoretical analysis are carried out to show the effectiveness of the gain-clamping mechanism in realizing the multiwavelength operation of the EDFL (C) 2011 Elsevier Ltd.
