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...
