TL;DR: In this article, a surface Green function matching analysis is used to make a detailed study of several different aspects of the surface-wave problem in anisotropic cubic crystals and new methods for calculating surfacewave velocities are introduced and used in practice.
Abstract: A surface Green function matching analysis is used to make a detailed study of several different aspects of the surface-wave problem in anisotropic cubic crystals. New methods for calculating surface-wave velocities are introduced and used in practice. Dynamic characteristics surface-wave thermodynamics and detailed spectral features of the surfacewave system are studied and reflection Brillouin scattering experiments are discussed on the basis of these. Part of the results obtained here corroborates previous theoretical work, but the analysis also bears new features not previously studied.

TL;DR: In this paper, a transverse stimulated Brillouin scattering (SBS) was observed in fused-silica optical components using 2.4-nsec pulses at 350 nm.
Abstract: Using 2.4-nsec pulses at 350 nm, we have observed transverse stimulated Brillouin scattering (SBS) in fused-silica optical components. Transverse SBS sets in when the product of laser fluence and growth time for the scattered optical wave exceeds ∼2.3 J nsec/cm2. An increase in laser bandwidth to 8.3 GHz suppresses SBS losses up to approximately twice the SBS threshold. We review the theory of transverse, broadband SBS and its scaling with experimental parameters.

TL;DR: The structural transformations occurring to water from low-density (LDW) to high- density (HDW) regimes have been studied by Brillouin scattering for the first time at temperatures up to 453 K and at pressures up to the solidification point.
Abstract: The structural transformations occurring to water from low-density (LDW) to high-density (HDW) regimes have been studied by Brillouin scattering for the first time at temperatures up to 453K and at pressures up to the solidification point. At ambient temperature (293K) a discontinuity in pressure response of the sound velocity is observed. Furthermore, there are evident breaks in the linear behavior of log10C11 versus log10(ρ∕ρ0) when pressure increases up to 0.29, 0.21, and 0.19GPa at the temperature of 293, 316, and 353K, respectively. It is supposed to indicate the structural transition from LDW to HDW, and the possible transition boundary between LDW and HDW is in good agreement with the molecular-dynamics simulation.

TL;DR: In this paper, a new optical unit structure which can suppress stimulated Brillouin scattering (SBS) is developed by distributing the fibre strain in the optical unit, which is the first proposal for suppressing SBS by cabling.
Abstract: A new optical unit structure which can suppress stimulated Brillouin scattering (SBS) is developed. The Brillouin gain bandwidth is expanded by distributing the fibre strain in the optical unit. The expansion depends on a unique strain-holding double-stranded optical unit structure. This is the first proposal for suppressing SBS by cabling. A 3.7 km long cable was laid in the sea and its Brillouin gain bandwidth was measured. The bandwidth was expanded 2.9 times with a cyclic strain amplitude of 0.08%. >
