Abstract:
We have measured fluorescence from a waveguide formed by a falling cylindrical
stream of liquid. The configuration is suited to taking measurements from
liquids with any refractive index, such as aqueous solutions. The parameters
which determine the stream stability have been investigated, and the optical
collection efficiency has been mathematically modelled. We have produced streams
up to 350 mm long with a 2.5 mm diameter, and measured a fluorescence collection
enhancement factor of 9 from a 100 mm long, 1 mm diameter stream.
