Multikilohertz stimulated Brillouin scattering

Optics Letters, 1994
We report, for the first time to our knowledge, multikilohertz stimulated-Brillouin-scattering phase conjugation of copper-vapor laser radiation. The small wavelength shift associated with the Stokes radiation is shown to permit double-pass aberration correction of the copper-vapor laser, avoiding the postlasing absorption.

Stimulated Brillouin Scattering

2022
Abstract Stimulated Brillouin scattering (SBS) is based on a gain mechanism provided by the pump light reflection from the induced hypersonic acoustic Bragg grating in a continuous net optical medium. The mathematic formulation of SBS generation is based on the solutions of the coupled wave equations that describe the pump field-induced ...

Stimulated Raman scattering enhanced by stimulated Brillouin scattering

Optics Letters, 2009
A 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 ...

Stimulated Brillouin Scattering in AlGaAs on Insulator Waveguides

Conference on Lasers and Electro-Optics, 2020
We observe stimulated Brillouin scattering (SBS) in AlGaAs-on-insulator integrated waveguides. A guided transverse acoustic mode has a 12.3 GHz Brillouin shift, and a full-width half-maximum of 25 MHz.

Two-dimensional stimulated Brillouin scattering

Physical Review E, 1994
The 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 ...
