Superchemistry: dynamics of coupled atomic and molecular Bose-Einstein condensates [PDF]

, 2000
We analyze the dynamics of a dilute, trapped Bose-condensed atomic gas coupled to a diatomic molecular Bose gas by coherent Raman transitions. This system is shown to result in a new type of `superchemistry', in which giant collective oscillations ...

Mode locking using stimulated Raman scattering

Optics Express, 2007
Recent experiments have shown that the simple addition of a length of Raman-shifting fibre in the cavity of a cw-pumped fibre laser can cause the laser to generate a stable train of pulses [Zhao and Jackson, Opt. Lett., 31 751 (2006)]. We show using a numerical model that this behavior is a new type of mode locking, driven by backward stimulated Raman ...

Dynamic optical bistability in resonantly enhanced Raman generation

, 2004
We report observations of novel dynamic behavior in resonantly-enhanced stimulated Raman scattering in Rb vapor. In particular, we demonstrate a dynamic hysteresis of the Raman scattered optical field in response to changes of the drive laser field ...

Stimulated Raman scattering excited by incoherent light in plasma

Matter and Radiation at Extremes, 2017
Stimulated Raman scattering (SRS) excited by incoherent light is studied via particle-in-cell simulations. It is shown that a large bandwidth of incoherent light can reduce the growth of SRS and electron heating considerably in the linear stage. However,

Mathematical Model of Amplified Stimulated Raman Scattering and Fiber Raman Amplifier

Iraqi Journal of Physics, 2008
The result of a developed mathematical model for predicting the design parameters of the fiber Raman amplifier (FRA) are demonstrated. The amplification parameters are tested at different pump power with different fiber length.

INVERSE SCATTERING TRANSFORM ANALYSIS OF STOKES-ANTI-STOKES STIMULATED RAMAN SCATTERING

, 1995
Zakharov-Shabat--Ablowitz-Kaup-Newel-Segur representation for Stokes-anti-Stokes stimulated Raman scattering is proposed. Periodical waves, solitons and self-similarity solutions are derived. Transient and bright threshold solitons are discussed.Comment:

Extreme Value Statistics in Silicon Photonics

IEEE Photonics Journal, 2009
L-shape probability distributions are extremely non-Gaussian functions that have been surprisingly successful in describing the occurrence of extreme events ranging from stock market crashes, natural disasters, structure of biological systems, fractals ...

Plasmon-enhanced stimulated Raman scattering microscopy with single-molecule detection sensitivity

Nature Communications, 2019
Stimulated Raman scattering (SRS) microscopy enables label-free chemical imaging at high speed, but has been limited by low sensitivity. Here, the authors demonstrate plasmon-enhanced SRS microscopy and achieve single molecule detection sensitivity.
