N2 - The photonic interactions between a focused Gaussian laser beam and a nanoscopic particle are highly dependent on exact particle location and focal intensity distribution. So far, the 3D focal intensity distribution and the preferred position of a nanoparticle confined within the focal region were only theoretically predicted. Here, we directly map the three-dimensional focal intensity distribution, quantify stable trapping positions, and prove that certain sizes of nanoparticles stably trap in front of the focus.
