摘要：
We demonstrate a double-clad Nd3+-doped polarization maintaining fiber (PMF) amplifier at 1064 nm for a compact configuration of a high-gain and low-noise optical fiber amplifier. The proposed 125 mu m inner-cladding diameter in the double-clad fiber provides the single-mode propagation of the signal lightwave into its doped core without misguiding the signal lightwave into the outer-cladding. The small signal gain of Nd3+-doped fiber amplifier is 24 dB, and its noise coefficient is less than 8 dB.
