In contrast to other nano-and micromechanical oscillators, the optically trapped nanoparticle in vacuum has no clamping losses, its motion is influenced only by a laser beam and its potential profile and therefore the mechanical quality factor of such oscillator is very high. In water solution, an optical trap can be considered as harmonic but in vacuum the optical potential anharmonicity starts to play an important role. This can be observed in power spectrum density profile where the oscillation peak is asymmetric. Here we show that commonly used method employing power spectrum density fitting for revealing the system parameters is not sufficient and other approach has to be developed.
