Elimination of Optical Self-Focusing by Population Trapping

Abstract

We demonstrate a method for eliminating optical self-focusing and defocusing for a copropagating pair of intense laser beams whose frequencies differ by a Raman resonance. The lasers force the atoms of the medium into a population trapped state, thereby eliminating their contribution to the nonlinear refractive index.

Raman self-focusing at maximum coherence

D. R. Walker, Deniz D. Yavuz, Miro Y. Shverdin +3 more

We demonstrate a type of Raman self-focusing and -defocusing that is inherent in operation at maximum coherence. In this regime the two-photon detuning from the Raman resonance controls the refractive index of the medium.

Observation of Raman self-focusing in an alkali-metal vapor cell

Nicholas Proite, Brett Unks, Jonathan Tyler Green +1 more

We report an experimental demonstration of Raman self-focusing and self-defocusing in a far-off resonant alkali-metal atomic system. The key idea is to drive a hyperfine transition in an alkali-metal atom to a maximally coherent state with two laser beams. In this regime, the two-photon detuning from the Raman resonance controls the nonlinear index of the medium.

Atomic self-trapping and self-focusing in a light medium

Weiping Zhang, Barry C. Sanders, Weihan Tan

Light-induced dipole-dipole interactions in a coherent atomic field result in an effective nonlinear interaction between atoms. This nonlinearity can induce self-focusing and self-trapping of a coherent atomic beam undergoing propagation through a travelling-wave laser beam; we show how such a scheme could be realized and evaluate the critical density required for atomic self-focusing and self- trapping. An analogy to optical self-focusing and self- trapping is discussed.

Optical pattern formation in self-focusing and self-defocusing diffractively thick media

G. Labeyrie, Ivor Krešić, Robin Kaiser +1 more

Cold atomic clouds constitute highly resonant nonlinear optical media, whose refractive index can easily be tuned via the light frequency. When subjected to a retroreflected laser beam and under appropriate conditions, the cloud undergoes spontaneous symmetry breaking, and spatial patterns develop in the transverse cross section of the beam. We investigate the impact of the sign of the light detuning from the atomic resonance on these patterns, thus directly comparing pattern formation for self-focusing and self-defocusing nonlinearities. Our observations emphasize the need for a ``diffractively thick'' medium description of the light-cloud interaction in which diffraction and nonlinear propagation inside the sample are taken into account.

Refractive Index Enhancement in a Far-Off Resonant Atomic System

Deniz D. Yavuz

We demonstrate a scheme where a laser beam which is very far detuned from an atomic resonance experiences a large index of refraction with vanishing absorption. The essential idea is to excite two Raman resonances with appropriately chosen strong control lasers.

Sensitivity enhancement of nonlinear refractive index measurement by Gaussian-Bessel beam assisted z-scan method

Wei Gao, Sandan Wang, Jinpeng Yuan +3 more

Characterizing the nonlinear optical properties of numerous materials plays a prerequisite role in nonlinear imaging and quantum sensing. Here, we present the evaluation of the nonlinear optical properties of Rb vapor by the Gaussian-Bessel beam assisted z-scan method. Owed to the concentrated energy in the central waist spot and the constant intensity of the beam distribution, the Gaussian-Bessel beam enables enhanced sensitivity for nonlinear refractive index measurement. The nonlinear self-focusing and self-defocusing effects of the Rb vapor are illustrated in the case of blue and red frequency detunings from 5S1/2 − 5P3/2 transition, respectively. The complete images of the evolution of nonlinear optical properties with laser power and frequency detuning are acquired. Furthermore, the nonlinear refractive index n2 with a large scale of 10−6 cm2/W is determined from the measured transmittance peak-to-valley difference of z-scan curves, which is enhanced by a factor of ∼ 1.73 compared to the result of a equivalent Gaussian beam. Our research provides an effective method for measuring nonlinear refractive index, which will considerably enrich the application range of nonlinear material.
