Abstract

The use of a laser to induce oscillations of an atomic force microscopy cantilever provides a way to excite the dynamics of the system in a very controlled manner. This excitation scheme has been used to obtain reliable self-sustained oscillations, in air and in liquid environments, and to implement an additional control loop leading to a soft, low-interaction, working mode. The dynamics of the oscillating cantilever has been characterized, both theoretically and experimentally, and the effectiveness of the approach has been verified on a test sample.
