A novel diffractive-pumping scheme is proposed to improve the evanescent amplification using blazed fiber grating for the first time. We also investigate the cw-pumped evanescent amplification at 1.55 µm wavelength with the relative optical gain pumped at 1480 nm of around 2 dB based on side-polished fiber with the effective interaction length as long as 16 mm and with a heavily Er³⁺-doped (N_Er³⁺>1.19×10²¹ ions/cm³), low refractive index (n₁₅₅₀<1.47) glass overlay, which has no concentration quenching (τ_f=9.0 ms).
