摘要

经过数十年的研究,目前已有近半打的高效泵浦稀土激光转换光纤激光器能够实现瓦特级输出。这些系统使用近红外激光二极管进行激励,并已发展成为可靠的高光束质量光源,其中一些已在市场上销售。中红外光纤激光器的成熟完全基于高质量的氟化玻璃光纤,这种光纤已成为发射波长达 4 µm 的主要光纤增益材料。其他主要的中红外透明玻璃系列、重金属氧化物和钙化物一直面临着氢向玻璃中持续扩散的挑战,这在中红外的高频部分产生了强烈的吸收特征。这一问题以及在充分浓缩稀土掺杂水平方面的挑战一直阻碍着光纤激光器在中红外发射方面的进展。近年来,由于在前驱体纯化和减少制造过程中的污染方面做出了巨大努力,使用这些玻璃进行的中红外激光演示取得了突破性进展,其发射波长现已超过 5 µm。因此,中红外光纤激光器研究进入了一个新时代,光纤的效率潜力、可靠性和相对简单的结构将带来更多突破和应用。

Mid-infrared fiber laser research: Tasks completed and the tasks ahead
After decades of research, there are almost half a dozen efficiently pumped rare earth laser transitions in a fiber laser format capable of Watt-level output. These systems use near-IR laser diodes for excitation and have developed into reliable sources of high beam quality light with some commercially available. This maturation of the mid-IR fiber laser is entirely based on a high quality fluoride glass fiber, which has emerged as the primary fiber gain material for emission up to 4 µm. The other major mid-IR transparent glass families, the heavy metal oxides, and chalcogenides have always been challenged by consistent hydrogen diffusion into the glass that creates strong absorption features in the high-frequency portions of the mid-IR. This problem along with challenges to sufficiently concentrate the rare earth doping level has historically stifled progress preventing fiber laser emission in the mid-IR. In recent years, great efforts in precursor purification and reducing contamination during fabrication have resulted in pioneering demonstrations of mid-IR lasing using these glasses with emission now extending beyond 5 µm. As a result, mid-IR fiber laser research has entered a new era with more breakthroughs and applications to benefit from the efficiency potential, reliability, and relatively simple architecture of the optical fiber.
