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 ($N_{\text{Er$^{3+}$}}>1.19\times 10^{21}$ ions/cm3), low refractive index ($n_{1550}<1.47$) glass overlay, which has no concentration quenching ($\tau_{\text{f}}=9.0$ ms).
