Phonon-Dressed Third-harmonic Generation in Diamond

Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses

Published Jan 1, 2023• 0 citations
Publisher

Abstract

We experimentally demonstrate in diamond that third-harmonic generation can be enhanced by orders of magnitude with polarization dependence through assistance from a Raman resonance, in a process analogous to coherent anti-Stokes Raman scattering.

Lifetime and polarization for real and virtual correlated Stokes-anti-Stokes Raman scattering in diamond

The correlation between the Stokes and anti-Stokes components of Raman scattering has assumed an important role in the field of quantum information. When the Raman shifts match the energy of a phonon in the material, in the real-SaS, one-phonon Fock state are generated. When such resonance is not achieved, the energy exchange is mediated by virtual phonons, generating photonic Cooper pairs (PCPs). In this work, investigations of polarization correlations and scattering time dependences elucidate the fundamental difference between the real and the virtual phenomena.

Investigation of anti-Stokes Raman processes at phonon-polariton resonance: from Raman oscillation, frequency upconversion to Raman amplification

Yujie J. Ding

Raman oscillation, frequency upconversion, and Raman amplification can be achieved in a second-order nonlinear medium at the phonon-polariton resonance. By beating two optical fields, a second-order nonlinear polarization is generated inside the medium. Such a polarization induces a spatially uniform nonpropagating electric field at the beat frequency, which in turn mixes with the input optical field at the lower frequency to generate or amplify the anti-Stokes optical field. Raman oscillation can be efficiently reached for the copropagating configuration. In comparison, efficient frequency upconversion and large amplifications are achievable for the counterpropagating configuration. These Raman processes can be used to effectively remove transverse-optical phonons before decaying to lower-frequency phonons, achieve laser cooling, and significantly enhance coherent anti-Stokes Raman scattering. The counterpropagating configuration offers advantages for amplifying extremely weak signals.

Physical Properties of Photonic Cooper Pairs Generated via Correlated Stokes–anti‐Stokes Raman Scattering

Filomeno Soares de Aguiar Júnior, Carlos Henrique Monken, Marcelo França Santos +4 more

The theoretical and experimental background for the creation of photonic Cooper pairs (PCPs) via correlated Stokes–anti‐Stokes Raman scattering is introduced, followed by experimental results on the second‐order photon time correlation g2(0) in diamond. It is shown how g2(0) changes with energy (Stokes–anti‐Stokes Raman shift), momentum (scattering angle) and excitation laser power. Both real and virtual phonon‐mediated scattering processes are addressed.
