Airyprime beam: From the non-truncated case to truncated one
摘要： The present paper investigates the spatial proprieties of a novel beam introduced recently known as Airyprime beam, its on-axis and transverse intensities are studied numerically. It is shown that the focused Airyprime beam exhibits two focuses corresponding to two intensities maxima limiting an Optical Bottle Beam (OBB), the latter is characterized by its length where numerical examples show that we can adjust and change it by changing the scale parameter w x0 which is related directly to the input width of the Airyprime beam. The spatial proprieties of the truncated Airyprime beam are also studied; by acting on the aperture diameter one can modify the on-axis intensity to choose between a mono focus beam and dual focus beam. Depending on the aperture diameter the Airyprime beam is transformed into other interesting laser beam patterns such as, a ?attop beam, Gaussian beam, and tune Optical Bottle Beam. The Airyprime beam could be interesting tool of trapping and guiding microparticles.

Spatial characteristics of the truncated circular Airyprime beam
摘要： The circular Airyprime (CiAiP) beam is introduced in this paper. The spatial proprieties are well discussed and compared to the first order radial Laguerre–Gaussian beam LG10. The width, the divergence and the beam propagation factor are calculated based on the second order moments method, the latter is equal to M2 = 3.08. The free propagating CiAiP beam exhibits an unexpected non-diffracting character, it doesn’t spread through propa- gation. The on-axis intensity of the focused circular Airyprime beam is also explored, it exhibits a dual focus corresponding to two on-axis intensity maxima, it could be modified under diffraction using a hard circular aperture. The latter presents a cheap beam shaper, it is shown that a hard aperture could transform an input circular Airyprime beam into per- fect ringed beam, a perfect Gaussian beam and a top hat beam. By combining the axial and the transversal behavior of a truncated circular Airyprime beam for a particular aperture diameter a perfect cylindrical optical bottle beam is obtained. The present work could be of big interest in the field of structured light.
