论文摘要
将微流体分析物提供与集成光学分析相结合的实验室芯片(LOC)设备对于生物ODER医学科学的多种应用非常可取。虽然微流体方法已经广泛地受到了最大的影响,但是对于集成的光学器件,尤其是提供高度集成的激光源,需要做一些工作。聚合物光纤(POF)激光器代表了一个无对齐,坚固且灵活的技术平台。另外,POF与聚合物微流体设备本质上兼容。自制的若丹明B(RB)掺杂的POF的特征是其激光潜力的实验和数值参数研究。高输出能量为1.65MJ,从RB:POFS提取了<900 K的高坡度效率56%和50%的高度效果。此外,RB:POF在几十纳米上显示出广泛的光谱可调性。揭示了一种优化聚合物纤维激光器的途径,可为广泛的LOC设备提供功能。光谱可调性,高效率和输出能量可以实现广泛的LOC应用领域。
Lab-on-a-Chip (LoC) devices combining microfluidic analyte provision with integrated optical analysis are highly desirable for several applications in biological oder medical sciences. While the microfluidic approach is already broadly adressed, yet some work needs to be done regarding the integrated optics, especially provision of highly integrable laser sources. Polymer optical fiber (POF) lasers represent an alignment-free, rugged and flexible technology platform. Additionally, POFs are intrinsically compatible to polymer microfluidic devices. Home-made Rhodamine B (RB) doped POFs were characterized with experimental and numerical parameter studies on their lasing potential. High output energies of 1.65mJ, high slope efficiencies of 56% and 50%-lifetimes of < 900 k shots were extracted from RB:POFs. Furthermore, RB:POFs show broad spectral tunability over several tens of nanometers. A route to optimize polymer fiber lasers is revealed providing functionality for a broad range of LoC devices. Spectral tunability, high efficiencies and output energies enable a broad field of LoC applications.
