HIGHLIGHTS
- who: K. Krupa and colleagues from the Institut Sciences, ulKasprzaka, Warsaw, Poland. Sapienza University have published the Article: Spatial Beam Self-Cleaning in Second-Harmonic Generation, in the Journal: Scientific Reports Scientific Reports of 31/03/2020
- what: The authors experimentally demonstrate a novel mechanism for nonlinear spatial self-cleaning of a highly multimode (i.e., comprising a large number of spatial frequency components) optical beam into the plane wave mode or component, based on the process of second-harmonic generation (SHG) in a quadratic nonlinear optical crystal. Surprisingly, here the authors show that nonlinear . . .
