Investigation and characterization of single hot spot laser-plasma interactions
… the Langmuir decay instability (LDI) cascade and stimulated scattering off of an acoustic-like electron mode below the usual electron plasma wave frequency. The LDI is the result of the electron plasma wave (EPW) generated by stimulated Raman scattering (SRS) growing to a sufficient amplitude such …

Propagation Effect In Inhomogeneous Media, Including Media With Light-induced And Fixed Gratings
… Orientational Nonlinearity in Liquid Crystal) Stimulated Scattering is numerically observed. Two diffractive optical elements made of volume gratings are suggested and analyzed. A transmission hologram based on the analogy with Stimulated Raman Adiabatic Passage (STIRAP) in nonlinear optics is …

The study of acoustic properties of P205-doped silica fiber
… in several of these applications. A significant stimulated scattering mechanism observed is stimulated Brillouin scattering (SBS), resulting in strong backward scattering typically within the optical fiber core. SBS has become one of the significant factors limiting the power transmitted in an …

Time and temperature dependence of stimulated brillouin scattering in fused silica
Several aspects of stimulated Brillouin scattering which relate to the determination of acoustic phonon lifetime (Tp) have been investigated. Fused silica was selected as the principal material to be studied because of its optical and acoustic isotropy and its availability in large, optical quality …

Spin and lattice properties of optically trapped exciton polaritons
… They are compound bosons for which stimulated scattering and macroscopic occupation of single quantum states can occur at sufficiently high densities. One way of creating such polariton condensates is with nonresonant optical pumping. Doing so creates a large density of free- …

Optical study of shear and longitudinal acoustic waves and complex relaxation dynamics of glass forming liquids
The spectroscopic technique Impulsive Stimulated Scattering (ISS) was refined and used to study the complex structural relaxation dynamics of glass forming liquids, allowing both empirical modeling and testing of the predictions of the mode-coupling theory (MCT). Longitudinal and shear acoustic …

Applications Of Linear And Nonlinear Optical Effects In Liquid Crystals
… of beam combining using Orientational Stimulated Scattering in a nematic liquid crystal cell. Our numerical study of the OSS process shows that normally this possibility does not exist. However, we found that if a number of special conditions is satisfied efficient beam combining with …
