a Schematic of the setup for parallel laser heating, shaping and temperature microscopy. b Sample geometry, consisting of an AttofluorTM chamber containing a coverslip covered with gold nanoparticles. c Close look at the sample (not to scale). d Representation of a uniform laser beam profile and (e) simulation of the subsequent temperature distribution at the gold nanoparticle sample plane. f Representation of a ring-like laser beam profile suited for uniform temperature generation, as shown in the simulation of the resulting temperature distribution displayed in (g). Scale bars: 30 µm.
