Generation of a high-quality partially coherent dark hollow beam with a multimode fiber
TL;DR: The experimental generation of a high-quality partially coherent dark hollow beam (DHB) is reported by coupling a partially coherent beam into a multimode fiber (MMF) with a suitable incidence angle by closely controlled coherence of the input beam.

Generation of tunable chain of three-dimensional optical bottle beams via focused multi-ring hollow Gaussian beam.
TL;DR: The generation of a chain of three-dimensional (3-D) optical bottle beams is reported by focusing a π-phase shifted multi-ring hollow Gaussian beam (HGB) using a lens with spherical aberration to demonstrate tunability in the size and the periodicity of the 3-D optical bottles over a wide range.

TL;DR: A compact, all-solid-state 532 nm semi-Gaussian laser beam (SGB) source based on a 1064 nm laser and a transversely varying periodically-poled LiTaO3 (TPPLT) crystal as the laser beam shaper as well as the nonlinear frequency converter is experimentally demonstrated.
