Noble-metal nanoparticles show large optical resonances associated with surface plasmons (SP's), i.e. collective oscillations of conduction electrons [1], Ellipsoidal nanoparticles with axis dimensions a=b<c (so-called spheroids) show two different SP's which lie at different wavelengths for light polarized parallel to the short and long axes, respectively. In the present contribution, we show for the first time that: (i) these two different collective excitations influence each other via hot-electron processes, (ii) coherent lattice vibrations of two different energies can be optically generated in the ellipsoids.
