Can we cancel light waves?
Stefan Rotter, theoretical physicist exploring anti‑lasers and perfect absorbers. Jeremy Baumberg, nanophotonics expert who manipulates light with hands‑on demos. They discuss destructive interference with lasers, the anti‑laser that traps and absorbs coherent light, and why cancelling everyday incoherent light like sunlight is far more challenging.
