Motion of optically levitated nanoparticle in nonlinear regime

Popis výsledku v původním jazyce

Optically levitated nanoparticles in vacuum have gained much attention for their ultrasensitivity to forces of zN.Hz(-1/2) orders and for the potential investigation in the field of quantum physics. In contrast to other nanoand micromechanical oscillators, the optically trapped nanoparticle in vacuum has no clamping losses, its motion is influenced only by a laser beam and its potential pro file 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 pro file 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.
