We present results describing the behavior of optically trapped airborne particles, both solid and liquid. Using back focal plane interferometry we measure characteristic power spectra describing the position fluctuations within the trap. We show it is easy to transfer between an over and under damped regime by either varying the trapping power or the distance into the medium the beam is focused. The results assist in the understanding of airborne tweezers and it is hoped having under damped systems could lead to exploring analogies in many areas of fundamental physics.
