作者报告了使用微流控染料激光器对低浓度分析物的吸收测量。激光腔由两个金反射镜组成，这两个反射镜涂在插入芯片的两根光纤的端面上。罗丹明6G染料分子溶解在乙醇中用于激光放大和吸收测量用亚甲基蓝染料溶液完成。在532 nm波长的倍频Nd:YAG激光泵浦下，器件的激光输出波长为565 nm，激光输出对腔内损耗具有较高的灵敏度，与数值计算结果吻合较好。
The authors report absorption measurements on low concentration analytes using a microfluidic dye laser. The laser cavity is made of two gold mirrors coated on the end faces of two optical fibers inserted in a chip. Rhodamine 6G dye molecules dissolved in ethanol are used for laser amplification and absorption measurements are done with methylene blue dye solutions. When optically pumped with a frequency doubled Nd:YAG laser at 532 nm wavelength, the device shows a laser output emission at 565 nm and a high sensitivity of the lasing output to the losses in the cavity, in good agreement with the results of numerical calculations.
