“…Note that the research of pumping by the Bessel beam revealed new possibilities to control the angular profile of an amplified signal [10]. Here, we reveal new interesting features, namely, that the incoherent conical beam may act on the amplified signal beam as a plane wave giving rise to exponential amplification.…”

Optical parametric amplification of an input narrowband signal beam in the field of a spatially incoherent conical pump is investigated. Two amplification regimes -onset and exponential -are distinguished. The possibility to amplify the signal beam significantly and obtain a smooth intensity profile at the output is revealed. It is shown that the incoherent conical beam may act on the signal beam as a plane wave. Good agreement of theoretical and experimental data is obtained.

“…Classical parametric amplification with a conical-beam pump has been studied in the literature (see, for example, Ref. [29] and references therein). However, to the best of our knowledge, the quantum correlations between the axial probe beam and the conical conjugate beam in the FWM are experimentally demonstrated in this Letter for the first time.…”

Generation of multimode quantum states has drawn much attention recently due to its importance for both fundamental science and the future development of quantum technologies. Here, by using a four-wave mixing process with a conical pump beam, we have experimentally observed about -3.8 dB of intensity-difference squeezing between a single-axial probe beam and a conical conjugate beam. The multi-spatial-mode nature of the generated quantum-correlated beams has been shown by comparing the variation tendencies of the intensity-difference noise of the probe and conjugate beams under global attenuation and local cutting attenuation. Due to its compactness, phase-insensitive nature, and easy scalability, our scheme may find potential applications in quantum imaging, quantum information processing, and quantum metrology.
