“…The relative intensity squeezing between the probe and the conjugate beams can also be generated based on this configuration. [7][8][9][10][11] Now let us consider what happens when we apply a bias magnetic field to the Rb atoms. Suppose that the magnetic field is applied longitudinally.…”

We present an experimental study of multi-Raman gain resonances in a hot rubidium vapor. The experiment is performed based on a high-efficiency four-wave mixing process due to the Raman-driven coherence in a double-Λ configuration. The Raman gain resonance for 85 Rb atoms under a bias magnetic field is shown to be split into five or six peaks, depending on the orientation of the magnetic field. The formed multi-Raman gain resonances have potential applications in measurement of magnetic fields and generation of multi-frequency correlated twin beams.

“…It has been proven that the FWM process assisted by the ARG can amplify the input probe field and produce a phase conjugate field simultaneously. A scheme can also be used to generate bright correlated twin beams, [7][8][9][10][11] which are an important quantum resource for developing practical quantum information protocols.…”

“…In ARG, the probe field operates in a stimulated Raman emission mode. It has been proven by several groups [19][20][21][22] that the FWM process assisted by ARG can amplify the input probe field and produce a phase conjugate field at the same time. The relative intensity squeezing between probe and conjugate beams has been proved in this configuration.…”

We present the experimental generation of twin Airy beams with a phase insensitive parametric amplifier, which is based on a four-wave mixing process assisted by active Raman gain in a hot rubidium vapor cell. In our experiment, the seeded probe beam is an Airy beam which is amplified in this process, and an Airy conjugate beam is simultaneously generated. The self-healing property of the amplified probe and the generated conjugate beams are examined. The results are interesting for application of such beams in many fields such as quantum imaging and quantum information.

We experimentally investigate the frequency conversion of vector beams with four-wave-mixing (FWM) in rubidium vapor. The conversion of vector beams from the probe beam to the conjugate beam is realized. In FWM experiments, the pump and the probe beam have orthogonal polarizations because of the polarization sensitivity of the FWM process and detection convenience. In order to satisfy the polarization sensitive phase matching condition and realize the nonlinear frequency conversion of vector beams, a Sagnac interferometer is used to form two FWM processes in the same rubidium cell, and two generated conjugate beams are combined with a polarizing beam splitter to form a conjugate vector beam. The experimental results agree well with our theoretical simulation. Compared with nonlinear optical crystals, the atomic vapor provides another platform to control and manipulate the vector beams nonlinearly.
