We report stimulated Brillouin scattering (SBS) measurements in orbital angular momentum (OAM) carrying modes of an optical fiber. The additional degree of freedom afforded by angular momentum selectivity leads to new possibilities to control SBS gain. We find that, depending on the OAM value in relation to the polarization state of the launched pump light, the SBS threshold can vary by as much as 2.6 dB, even when normalized for mode area. Combined with their inherently large mode areas and naturally polarization maintaining behavior, OAM fiber modes may offer an alternative means for scaling power in narrow-linewidth fiber lasers.
