| Abstract: | We present a simple analytical model to describe the stimulated Raman Stokes scattering (SRS) linear polarization spectroscopy of fluorescent dye solutions in liquid‐core optical fibers (LCOFs). In this scheme, the linear polarization direction of the pump pulse is set parallel to the y‐axis through a straight polarization‐maintaining LCOF, in which the energy of the total optical field  is kept invariant, and different fluorescence dyes are used to generate different first‐order Stokes intensities. We demonstrate the SRS of all‐trans‐β‐carotene and fluorescein in carbon disulfide (CS2) solutions due to the optical field‐induced reorientation effect, which makes the first‐order Stokes polarization direction rotate by an angle of 88° or 61°, respectively. This demonstrates the good agreement between the theory presented and the experiment. Copyright © 2010 John Wiley & Sons, Ltd. |
