Stimulated Raman scattering of colored chaotic light
نویسندگان
چکیده
The quantum theory of forward Stokes generation by means of stimulated Raman scattering is extended to the case of a colored (finite-bandwidth) chaotic pump, which has both amplitude and phase fluctuations. In both transient and steady-state limits the mean Stokes intensity is found to be enhanced over that resulting from a coherent pump. In the limit that the chaotic-pump bandwidth becomes large, the mean Stokes intensity becomes identical with that resulting from a coherent pump of the same total power.

Thermal Effects Study on Stimulated Brillouin Light Scattering in Photonic Crystal Fiber
we investigate the temperature-dependences of the Brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. Positive dependences coefficients of 0.77, 0.56 and 1.45MHz/0C are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. The results indic...
متن کاملStimulated forward Raman scattering in large scale-length laser-produced plasmas
A forward stimulated Raman scattering (FSRS) diagnostic was developed for the 60 beam Omega laser facility to investigate the propagation of an intense (∼8x10 W/cm), frequency doubled Nd:glass laser beam (≤360 J, 527 nm, 1 ns) through a mm-scale laser-produced plasma. Forward scattered light was measured with spectral, and temporal resolution using a streaked spectrometer and an absolutely cali...
متن کاملEntanglement in the Process of Stimulated Brillouin Scattering of Light
Spontaneous Brillouin scattering which is considered to be a scattering of light at the acoustic waves caused by thermal fluctuations was investigated in 1922. Physically stimulated Brillouin scattering (SBS) is analogous to another type of stimulated scattering of light stimulated Raman scattering (SRS) of light in which the laser light is scattered by the vibrational mode of the medium. The m...

LLE Review, Volume 74 113 Laser–plasma instabilities1 are important in the field of inertial confinement fusion2 because they scatter laser light away from the target, which reduces the laser energy available to drive the compression of the nuclear fuel, or generate energetic electrons that preheat the fuel, which makes the fuel harder to compress. In stimulated Raman scattering an incident, or...

The magnetic sublevel specific preparation of the uX Sg 1 ,v51,J51& state of molecular H2 using stimulated Raman pumping with circularly polarized light to saturate the Q01(1) transition is reported. The intensities of S branch rotational Raman scattering signals for the v50 and v51 states combined with their depolarization ratios measured as a function of pumping light polarization provide dir...
