In both spontaneous Raman and Hyper-Raman scattering from isotropic systems, scattering due to one of the spherical tensor invariants cannot be eliminated. It is shown that these invariants can be eliminated through use of an appropriate experimental geometry in coherent Raman and hyper-Raman scattering. Applications of this technique are presented.

Cooling Silicon Raman Lasers with Coherent Anti-Stokes Raman Scattering
Optics and Photonics News, 2007In this paper we present an original technique, to mitigate the heat dissipation in Raman lasers. The lasing mechanism of a Raman laser is stimulated Stokes Raman scattering (SSRS), where a pump photon is converted into a lower energy Stokes photon and a phonon or heat, the so-called quantum-defect heating.

Theory of Spontaneous and Coherent Raman Scattering
1998Abstract The universality of the phenomenon, the convenience of the experimental technique and the simplicity of the spectra obtained enable the effect to be used as an experimental aid to the solution of a wide range of problems in physics and chemistry.

Coherent versus incoherent Raman scattering: molecular coherence excitation and measurement
Optics Letters, 2007We present a comparative analysis of spontaneous and coherent Raman scattering on pyridine. The instantaneous excitation of the molecular coherence is done by a pair of ultrashort preparation pulses. Then, a long narrowband probe pulse is scattered off the molecular vibrations.

Broadband coherent anti-Stokes Raman scattering in silicon
Optics Letters, 2010In silicon devices, the spectral bandwidth of coherent anti-Stokes Raman scattering (CARS) is limited by the narrowband nature of the Raman process in this medium. In this Letter, we report the observation of broadband wavelength conversion in silicon through CARS enhanced by the self-phase-modulation-induced spectral broadening of the optical pump ...

Efficient hyper-Raman scattering in resonant coherent media
Optics Letters, 2003We propose and analyze a hyper-Raman scheme for generation of coherent light in a five-level atomic system based on electromagnetically induced transparency (EIT). We show that EIT suppresses linear and nonlinear photon absorption and enables the hyper-Raman process to proceed through real, near-resonant intermediate states. The scheme greatly enhances

Coherent Anti-Stokes Raman Scattering
1986The Raman effect is an inelastic photon-scattering process, in which an atom or molecule absorbs one photon while simultaneously emitting another photon at a different frequency. The emitted photon is at a frequency, w0, which can be greater or less than the frequency, w1, of the absorbed photon: (1) where Δw > 0.

Coherent Anti-Stokes Raman Scattering
1981The possibility of carrying out temperature and concentration measurements in gases by a Raman spectroscopy analysis was suggested and demonstrated about a decade ago. Following some early publications on this subject [1,2], a massive effort was undertaken in order to evaluate the potential of spontaneous Raman scattering in the important areas of ...
