An optical fiber heating device includes a heat producing fiber wrapped around a cell which is filled with an atom vapor.

Heating atom-vapor cell using an optical fiber

A system includes a laser () operative to emit a light beam, a beam splitter () arranged to split the light beam into a first beam and a second beam, the first beam being directed to a nonlinear converter () that generates a signal beam having a Stokes-shifted wavelength, a recombiner () arranged to recombine the signal beam with the second beam to form a recombined beam which is directed to a tapered optical fiber () located within a material to be monitored, and a detector () arranged to detect light emitted by the tapered optical fiber () and which uses stimulated Raman spectroscopy to detect a chemical in the material.
