基于在光束质量、效率和适用性方面的良好特性，光纤集成激光器在各种应用领域（例如学术界、工业、医疗技术和生命科学）中取代了昂贵的块状激光器。此外，稀土掺杂光纤具有较宽的增益区，为开发光谱学用宽调谐光纤激光器提供了巨大的潜力。最近，基于FBG阵列作为离散光谱滤波器的光纤集成调谐概念被证明，表现出独特的灵活性，以定制光谱和时间发射特性。在这项工作中，我们提出了这个概念的前景，以解决差分吸收激光雷达（DIAL）的环境传感。通过可调多波长操作以提高测量速度，并定制光谱发射线以探测特定分子，它可以提供具有出色可用性的快速且经济高效的解决方案。
Based on favorable properties with respect to beam quality, efficiency and applicability, fiber-integrated lasers replace costly bulk lasers in various application fields, such as in academia, industry, medical technology and life sciences. Additionally, rare-earth doped fibers exhibit broad gain regions, providing huge potential to develop broadly tunable fiber lasers for spectroscopy. Recently a fiber-integrated tuning concept based on an FBG array as discrete spectral filter was demonstrated, exhibiting a unique flexibility to tailor spectral and temporal emission properties. In this work, we present the prospects of this concept to address Differential Absorption LIDAR (DIAL) for environmental sensing. With tunable multi-wavelength operation for enhanced measurement speeds, and customized spectral emission lines to probe specific molecules, it may provide a fast and cost-efficient solution with excellent usability.
