Abstract:
We have investigated methods for reducing the threshold for stimulated Brillouin scattering SBS using a frequency-narrowed Cr,Tm,HoYAG 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.
