Beam Quality Factor of Partially Coherent Airy Beam in Non-Kolmogorov Turbulence

open access: yesAtmosphere, 2022
A universal formula of the beam quality factor for a partially coherent Airy (PCA) beam in non-Kolmogorov turbulence has been investigated. Results of numerical simulation display that expanding the internal scales of non-Kolmogorov turbulence is good ...

Zernike-coefficient extraction via helical beam reconstruction for optimization (ZEHBRO) in the far field

open access: yesHigh Power Laser Science and Engineering, 2023
The spatial distribution of beams with orbital angular momentum in the far field is known to be extremely sensitive to angular aberrations, such as astigmatism, coma and trefoil. This poses a challenge for conventional beam optimization strategies when a

The beam quality parameter of spirally polarized beams [PDF]

open access: yesJournal of Optics A: Pure and Applied Optics, 2008
Starting from the expression for the quality parameter of a superposition of two general fields, the case of beams that can be written in terms of the polarization basis introduced by Gori is investigated. Different types of this class of beam are studied and compared. In particular, spirally polarized beams are considered.

Research on beam quality control technology of 2 μm antimonide semiconductor laser

open access: yesFrontiers in Physics, 2022
Antimonide semiconductor laser is a new type of laser with unique advantages in the 2 μm band. However, employing FP cavities causes multiple transverse modes to degrade beam quality despite achieving higher power output.

Beam Quality of a Nonideal Atom Laser [PDF]

open access: yesPhysical Review Letters, 2006
We study the propagation of a non-interacting atom laser distorted by the strong lensing effect of the Bose-Einstein Condensate (BEC) from which it is outcoupled. We observe a transverse structure containing caustics that vary with the density within the residing BEC.
