Spasers are promising candidates for the realization of coherent energy sources at the nanoscale. By using a first‐principle formulation, the authors show that the emission from a spherical core‐shell spaser exhibits a wide range of counterintuitive dynamics. At high energy, the system acquires the character of a nanoparticle with an effective ‘spin’, characterized by the emission of ultrafast vortexes. The image shows a three‐dimensional snapshot of the energy distribution of an ultrafast vortex, spinning at the femto‐scale. This opens up a wide range of new applications of spasers as unidirectional information sources and new types of quantum simulators.
