A tunable random distributed feedback (RDFB) fiber laser operating at 1 μm is presented, which consists of a piece of ytterbium-doped fiber, a manual tunable filter and a 1-km-long single-mode fiber that provides RDFB. The wavelength of the RDFB fiber laser can be tuned continuously from 1040 to 1090 nm with a linewidth of about 0.4 nm. Power output maintains good flatness in the 50 nm tuning range, with fluctuations within 1 dB. It is the first reported tunable RDFB fiber laser working at 1 μm as far as we know.
本文介绍了一种工作在1μm波长的可调谐随机分布反馈（RDFB）光纤激光器，它由一段掺镱光纤、一个手动可调滤波器和一段提供RDFB的1公里长单模光纤组成。该RDFB光纤激光器的波长可在1040至1090nm范围内连续调谐，线宽约为0.4nm。在50nm的调谐范围内，功率输出保持良好的平坦度，波动在1dB以内。据我们所知，这是首次报道的工作在1μm的可调谐RDFB光纤激光器。
