Double stimulated Brillouin scattering

Physica Scripta, 1989
To explain discrepancies between experiments and standard theories of stimulated Brillouin scattering Zozulya, Silin, and Tikhonchuk [Sov. Phys. JETP 59, 756 (1984)] have suggested a parametric process called Double Stimulated Brillouin Scattering (DSBS).

Stimulated Brillouin Scattering

Applied Optics, 1969
Stimulated Brillotuin scattering, the efficient scattering of light from parametrically amplified therma acoustic waves, has found many valuable uses since its initial observation and identification. Among these uses are included the measurement of hypersonic velocities and absorption in the gigaherz frequency range, laser frequency shifting, laser Q ...

Broadband stimulated Brillouin scattering

Optics Communications, 1992
Abstract The effects of bandwidth (2–800 GHz) and spatial beam quality (2–70xdiffraction limit) on the threshold, reflectivity and phase conjugate fidelity of stimulated Brillouin scattering are investigated experimentally. Efficient scattering of poor beam quality, broadband radiation is demonstrated.

Forward stimulated Brillouin scattering

Journal of Applied Physics, 1988
Forward stimulated Brillouin scattering characteristics are formulated by an extension of the current theory. Angle-dependent gain functions are derived in collimated and focused pump geometries. The time of growth for forward scattering based on the derived gain functions is calculated by comparing the forward and backward intensity time scales.

High-sensitivity and high-specificity biomechanical imaging by stimulated Brillouin scattering microscopy

Nature Methods, 2019
Label-free, non-contact imaging with mechanical contrast and optical sectioning is a substantial challenge in microscopy. Spontaneous Brillouin scattering microscopy meets this challenge, but encounters a trade-off between acquisition speed and the ...

Transient effects on stimulated Brillouin scattering

Optics Letters, 1992
We present a detailed comparison of theory and experiment for transient stimulated Brillouin scattering for a pump pulse with Gaussian temporal profile. A new approach for measuring Brillouin linewidths is demon-strated, and an unexplained asymmetry is observed.

Noise initiation of stimulated Brillouin scattering

Physical Review A, 1990
We describe a theoretical model that shows how stimulated Brillouin scattering (SBS) is initiated by thermally excited acoustic waves distributed within a Brillouin-active medium. This model predicts how the SBS reflectivity, Stokes linewidth, and fluctuations in Stokes intensity depend upon the laser intensity and upon the physical properties of the ...

Forward stimulated Brillouin scattering in optical nanofibers

Journal of the Optical Society of America B, 2019
We comprehensively investigate the process of forward stimulated Brillouin scattering in nanofibers, considering the electrostrictive body force, electrostrictive pressure, and radiation pressure.

Tunable Fourier Domain Mode-Locked Optoelectronic Oscillator Using Stimulated Brillouin Scattering

IEEE Photonics Technology Letters, 2018
We propose and demonstrate a tunable Fourier domain mode-locked optoelectronic oscillator (OEO) using a frequency scanning microwave photonics filter (MPF) based on stimulated Brillouin scattering (SBS).

Stimulated-Brillouin-scattering properties of SnCl_4

Optics Letters, 1991
Common liquid Brillouin media have poor optical and physical stability when they are pumped at high average powers. We demonstrate that tin tetrachloride, SnCl4, is stable and shows no thermal defocusing at 1064 nm for 20-ns pulses at fluences of 3 J/cm2 and a pulse-repetition frequency of 10 Hz. To characterize this new stimulated-Brillouin-scattering
