532-nm laser pump 30-dB-gain Er-doped fiber amplifier

This paper reports the experimental results of a Er-doped amplifier using a self-made intercavity frequency doubling Q-switched(5-10KHz) Nd:YAG laser as the pump source, a 1.536?m LD as the signal source. A gain of 30dB was obtained for only 24.4mW of pump power.
