“…Various approaches to the generation of LHBs have been proposed since the demonstration of this beam was first realized by using the destructive interference between two light beams at the focus [16]. They were generated by the use of nonparaxial light [17][18][19], holograms [16,20], binary phase plates [21][22][23][24], conical refraction [25][26][27][28][29], a uniaxial crystal [30], partially coherent beams [31,32], a spatial light modulator (SLM) [33], surface plasmon polaritons [34,35], and a photon sieve [36], to form a desirable hollow axial structure. In phase modulation methods, the diffractive optical elements, such as the π-phase plate, are constructed by the binary elements or the binary bitmap of the SLM.…”

A succinct experimental scheme is demonstrated to generate a localized hollow beam by using a π-phase binary bitmap and a convergent thin lens. The experimental results show that the aspect ratio of the dark-spot size of the hollow beam can be effectively controlled by the focal length of the lens. The measured beam profiles in free space also agree with the theoretical modeling. The studies hold great promise that such a hollow beam can be used to cool trapped atoms (or molecules) by Sisyphus cooling and to achieve an optically-trapped Bose-Einstein condensate by optical-potential evaporative cooling.

In this paper, the incident beam called highdimensional circular hollow sinh-Gaussian (HD-CHsG) beam with a novel wavefront is proposed, which is determined by three parameters (m, σ0, σ1). Based on the Richards-wolf vector diffraction theory, it can be focused into a longitudinal polarized optical needle through a high numerical aperture lens. The effects of the three parameters (m, σ0, σ1) on the resolution and depth of focus of the longitudinally polarized optical needle are simulated and analyzed. In the condition of (m, σ0, σ1) = (8, 0.6, 0.125), a super-diffraction longitudinal optical needle with ultra-long focal depth (resolution 0.40λ, focal depth 18.36λ, depth-to-width ratio 45.9:1) is generated. In addition, compared with a radially polarized incident beam whose amplitude distribution is Gaussian and circular hollow sinh-Gaussian (CHsG) distribution, the resolution and depth of focus of the longitudinally polarized optical needle obtained by focusing the HD-CHsG beam are higher. Both simulations and experiments are carried out to demonstrate the availability of our method. Our findings are of great significance to the production, manipulation, and application of longitudinally polarized optical needle.

“…The distinct properties of HLB promote its application to the optical-trapping of particles [12], laser-driven ion acceleration [13], and the generation of terahertz radiation [14]. Several general techniques for producing HLB are conical refraction [15,16], uniaxial crystal [17], interferometer [18], and photon sieve [19]. Most of these techniques require complex and large-scale optical devices.…”

Vertical-cavity surface-emitting lasers that can be controlled to emit hollow laser beam in certain LP21 mode are proposed and fabricated. A circular inverted surface relief with precisely designed diameter and thickness is introduced through theoretical simulation. The fabricated device shows a stable single LP21 mode operation with excellent robustness of mode and power to temperature. Preliminary analysis attribute the excellent performance of the device to the inverted surface relief, leading to hollow near-field spot distribution.
