High-resolution digital control of highly multimode laser
Chene Tradonsky, Simon Mahler, Gaodi Cai +4
A rapid and efficient method for generating laser beams with controlled intensity, phase and coherence distributions is presented. It is based on a degenerate cavity laser in which…
Structured beams invariant to coherent diffusion
Slava Smartsev, Ronen Chriki, David Eger +2
Bessel beams are renowned members of a wide family of non-diffracting (propagation-invariant) fields. We report on experiments showing that non-diffracting fields are also immune t…
Dynamics of dissipative topological defects in coupled phase oscillators
Simon Mahler, Vishwa Pal, Chene Tradonsky +3
The dynamics of dissipative topological defects in a system of coupled phase oscillators, arranged in one and two-dimensional arrays, is numerically investigated using the Kuramoto…
Coherent diffusion of partial spatial coherence
Ronen Chriki, Slava Smartsev, David Eger +2
Partially coherent light is abundant in many physical systems, and its propagation properties are well understood. Here we extend current theory of propagation of partially coheren…
Complex Lasers with Controllable Coherence
Hui Cao, Ronen Chriki, Stefan Bittner +2
The invention of lasers 60 years ago is one of the greatest breakthroughs in modern optics. Throughout the years, lasers have enabled major scientific and technological advancement…
Rapid Phase Retrieval by Lasing
Chene Tradonsky, Oren Raz, Vishwa Pal +3
Reconstructing an object solely from its scattered intensity distribution is a common problem that occurs in many applications. Currently, there are no efficient direct methods to…
