1.06μm帯Ndドープファイバアンプ Nd-Doped Fiber Amplifier at 1.06μm
A key point to develop the Nd-doped fiber amplifier (NDFA) at 1.06pm, the Al co-doping in the Nd-doped fiber, is introduced at first. After reviewing its basic amplification and noise characteristics, various possible application systems are discussed, such as fiber sensing, gravitational wave detection, free-space laser communication and laser radar, for both a booster amplifier and a preamplifier to improve the optical handling power in the transmitter and the sensitivity in the receiver. Finally, results of the fiber transmission and the tunable fiber ring laser source experiments, as examples of the application, are reported.The NDFA will offer a compact, high efficient, polarization independent and beam-distortion-free amplifier in stead of solid-state laser amplifiers at 1.06μm.
