In this Letter, a ring-core erbium-doped fiber (RC-EDF), with two-layer\nerbium-doped structure, supporting up to the fourth-order orbital angular\nmomentum (OAM) mode is designed and fabricated for OAM mode multiplexed\namplification. Using the RC-EDF, the third- and fourth-order OAM modes\namplification with ultra-low differential mode gain (DMG) is demonstrated by\nobserving both the modal intensity and phase distribution and measuring the\nmodal gain under the fundamental mode core-pumping. The measured average gain\nof four modes (l=+3, -3, +4, -4) multiplexed amplification is higher than 19dB\ncover the C-band and the DMG is less than 1dB. Additionally, the gain of two\nconjugate OAM modes are almost the same under different pump power no matter\nthey are amplified simultaneously or separately.\n
