Stimulated Raman scattering enhanced by stimulated Brillouin scattering
Optics Letters, 2009A phenomenon of stimulated Raman scattering enhanced by stimulated Brillouin scattering is investigated experimentally. Also, this phenomenon is analyzed based on physical mechanisms. It is shown that the pumping effect of stimulated Brillouin scattering on backstimulated Raman scattering is a commonly existing rule regardless of the experiment ...

Two-dimensional stimulated Brillouin scattering
Physical Review E, 1994The evolution of the stimulated Brillouin scattering (SBS) instability in time and two spatial dimensions is studied analytically. An exact solution of the linearized equations governing SBS in a finite homogeneous plasma shows that this two-dimensional instability usually saturates because of the convection of the ion-acoustic wave, regardless of ...

Double stimulated Brillouin scattering
Physica Scripta, 1989To 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, 1969Stimulated 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, 1992Abstract 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, 1988Forward 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.

Transient effects on stimulated Brillouin scattering
Optics Letters, 1992We 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, 1990We 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 ...

Stimulated-Brillouin-scattering properties of SnCl_4
Optics Letters, 1991Common 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
