Methods for SBS Threshold Reduction

Abstract

We have investigated methods for reducing the threshold for stimulated Brillouin scattering (SBS) using a frequency-narrowed Cr,Tm,Ho:YAG laser operating at 2.12 micrometers. The SBS medium was carbon disulfide. Single-focus SBS and threshold reduction by using two foci, a loop, and a ring have been demonstrated. Theories for the loop-SBS and the ring-SBS geometries have been developed and compared with experimental results. Backscatter power, energy, and conjugate fidelity data are presented.
