Optical pulling force

WebAn optical force is well known for its ability to “trap” or “propel” microscopic particles (1–26). A counterintuitive phenomenon was discovered in 2011 (27–31): By redirecting the incident photons forward, the light-induced Lorentz force can pull distant objects backward against the propagation of light. WebAug 10, 2024 · force or optical pulling force (OPF) occurs whenever illu- minated particles are pulled towards the source due to the momentum conservation. In contrast to the trapping force in optical...
