| 摘要: |
| 高非线性光纤制造技术的成熟和光纤激光器性能的提升,极大地促进了超连续谱光源的快速发展,以光纤为非线性介质的超连续谱的产生成为当前研究热点。从可见光、近红外和中红外3个不同波段,综述了超连续谱产生的技术方案与最新进展。当前,可见光和近红外波段的超连续谱光源输出功率已经突破百瓦量级,并出现了多芯光子晶体光纤、光纤放大器和随机光纤激光器产生超连续谱等众多新方案；以氟化物光纤和亚碲酸盐光纤为非线性介质的中红外超连续谱,输出功率也突破了十瓦量级；在光谱拓展方面,以硫系光纤为非线性介质的超连续谱,输出光谱已扩展到12 μm以上。 |

| Abstract: |
| Along with the maturity of high-nonlinearity optical fiber manufacturing technology and the improvement of the performance of fiber lasers, the supercontinuum sources have entered a period of rapid development. Supercontinuum generation by using optical fibers as the non-linear media has become a research hotspot. The technical schemes and recent progress of supercontinuum generation were been reviewed from three different bands:visible, near-infrared and mid-infrared. At present, the output power of the visible and near-infrared supercontinuum sources broke through 100 W. At the same time, many new schemes such as supercontinuum generation in multi-core photonic crystal fibers, fiber amplifiers and random fiber lasers were developed. The output power of mid-infrared supercontinuum generation by using fluoride and tellurite fibers as non-linear media, also reached 10 W. The output spectrum of supercontinuum generation with chalcogenide optical fibers as non-linear medium was extended to more than 12 μm. |
