Abstract: Provided are a design method and a device for minimizing noise of mode-locked fiber lasers by minimizing the length of a non-gain fiber. The method for minimizing noise of mode-locked fiber lasers comprises: reducing a non-linear effect and a pulse width by reducing the length of a non-gain fiber inside an optical fiber laser than a predetermined length; compensating for dispersion generated in the optical fiber laser using at least one of a diffraction grating pair and a chirp mirror; and setting the optical fiber laser as a stretched-pulse mode locking condition by adjusting the position of a polarizing plate.
