Abstract

This paper reports a tunable three-dimensional (3D) liquid-liquid waveguide laser constructed by two flow streams in a microchannel. It comprises a 3D dye dissolved liquid-liquid waveguide as gain medium and gold (Au) mirrors to provide feedback. The 3D liquid-liquid waveguide is highly efficient to overcome the optical loss as compared with liquid-liquid three-dimensional (2D) waveguide. The lasing wavelength is tuned by the refractive index of the liquid core flow stream, and the output energy can be varied by changing the volume ratio between the two flow streams. It has wide applications in biomedical, biological and chemical analyses in the near future.
