TLDR
In this article, a generalization of the Bessel beam that can be more efficient for nonlinear optical interactions has been proposed, where the intensity-length product is larger for asymmetric beams but still maintains the advantageous characteristics of the bessel beam, such as an extended longitudinal focus and a well defined angle with respect to the z-axis.Abstract:
We have shown that there exists a generalization of the Bessel beam that can be more efficient for some nonlinear optical interactions. The intensity-length product maybe larger for asymmetric beams but still maintains the advantageous characteristics of the Bessel beam, such as an extended longitudinal focus and a well-defined angle with respect to the z-axis.read more

Diffraction-free beams.
TL;DR: The first experimental investigation of nondiffracting beams, with beam spots as small as a few wavelengths, can exist and propagate in free space, is reported.

Tunable stimulated Raman scattering by pumping with Bessel beams.
TL;DR: Frequency tuning of SRS from polaritons in LiIO(3) by variation of the Bessel beam cone angle is demonstrated and the generation mechanism of the Stokes beam is identified as being due to noncollinear scattering of the component plane waves that constitute the Besse beam.

TL;DR: In this article, the authors studied three-photon resonance enhancement of third-harmonic generation and multiphoton ionization in xenon under excitation by the Bessel and the focused annular laser beams.

Self-phase-matching mechanism for efficient harmonic generation processes in a ring pump beam geometry.
TL;DR: The ring-shaped beam is shown to provide self-organized phase matching for a wide range of refractive index variation, which may automatically compensate the spatially nonuniform phase mismatch created by the optical Kerr effect.
