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…
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…
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…
Spatio-Temporal Supermodes:Rapid Reduction of Spatial Coherence in Highly Multimode Lasers
Ronen Chriki, Simon Mahler, Chene Tradonsky +3
Spatial coherence quantifies spatial field correlations over time, and is one of the fundamental properties of light. Here we investigate the spatial coherence of highly multimode…
Conversion of out-of-phase to in-phase order in coupled laser arrays with second harmonics
Chene Tradonsky, Micha Nixon, Eitan Ronen +4
A novel method for converting an array of out-of-phase lasers into one of in-phase lasers that can be tightly focused is presented. The method exploits second harmonic generation a…
