Abstract
The influence of beam-pointing on scanning confocal microscopy is investigated. The beam displacement is measured using a quadrant photodiode, and the apparent movement of a sub-micron-sized particle observed by second-harmonic microscopy is linked to the beam displacement. A simple beam-pointing stabilization is implemented, and improvement of beam stability by three orders of magnitude on long time scales is achieved.
