Annotation	Single beam optical trap (also known as optical tweezers) is created by a laser beam that is tightly focused by microscope objective with high numerical aperture. A dielectric particle in water medium is then dragged by optical forces to place of the highest optical intensity, i.e. to the laser beam focus. Photonic force microscopy (PFM) is a technique that utilizes optical tweezers for confining the local probe, usually a dielectric particle of a sub-micron diameter. I.e. PFM belongs to the of large family of scanning probe microscopy (SPM) techniques. We have used fluorescently labeled polymer sphere in order to conveniently measure the distance between the particle center and the focal point of the laser beam. To make the measurement more precise, we have measured two-photon-fluorescence, which is quickly decreasing with the probe-focus distance.
