光流体染料激光器可能在许多领域的未来激光应用中发挥重要作用，将波长灵活性与集成和易于操作相结合。然而，到目前为止，还没有全光纤集成染料激光器被证明。在本文中，我们报告了一系列的光流体全光纤罗丹明光源工作在重复频率高达1 kHz。通过在光激发期间循环罗丹明染料来避免染料漂白。激光辐射通过传统光纤提取，该光纤与填充染料的毛细管活性介质接合。通过调整实验装置，实现了一个可调谐的放大自发辐射源、一个多模激光器和几个横模激光器。阈值泵浦能量低至1 μ J，斜率效率高达mu 9%，表明在光谱学和生物医学等领域的实际应用潜力。(C)2015年美国光学学会
Optofluidic dye lasers may play a significant role in future laser applications in numerous areas, combining wavelength flexibility with integration and ease of operation. Nevertheless, no all-fiber integrated dye lasers have been demonstrated so far. In this paper, we report on a series of optofluidic all-fiber Rhodamine optical sources operating at a repetition rate as high as 1 kHz. Dye bleaching is avoided by circulating the Rhodamine dye during optical excitation. The laser radiation is extracted via conventional fibers that are spliced to the dye-filled capillary active medium. A tuneable amplified spontaneous emission source, a multimode laser, and a few transverse-mode laser are demonstrated by adjusting the setup. Threshold pump energies as low as similar to 1 mu J and slope efficiencies of up to mu 9% were obtained, indicating the potential for realworld applications in areas such as spectroscopy and biomedicine.
