Abstract :
An erbium-doped fiber amplifier with a high small-signal gain of 42 dB at the gain peak of 1536.4 nm, a pumping efficiency of 1.6 dB/mW, and an output saturation power of 10 dBm is obtained with a pump power of 60 mW at 532 nm using the second harmonic of a Nd:YAG laser as the pump source. These experimental results indicate that diode-laser-pumped mini-Nd:YAG lasers with intracavity frequency-doubling have an output power at 532 nm of 100-150 mW that can be of great interest for practical system applications using high-gain, high-output-power erbium-doped fiber amplifiers.<>
