When operated in vacuum, they become excellent low dissipation optomechanical
objects, with minimal thermal contact to the environment. Levitated optomechanics is considered the most promising platform for studying high-mass quantum physics, including macroscopic entanglement of two massive objects. Also, optically trapped nanoparticles represent the testbed for nanoscale stochastic processes. No matter what the application is, the experimenters face the problems of preparation, characterization and control of mechanical system. We present experimental realization of microscale system of two coupled oscillators, which is made up of two optically levitated and optically bound micro-particles. We reach air pressure for which the normal-mode splitting start to occur and show, that an active control of the system needs to be employed in order to prevent particle collision while decreasing the pressure even more. We introduce a Bayesian inference based framework, which uses the measured stochastic trajectories of the micro-particles to estimate the optical forces acting on them. Although this framework was inspired by the need for characterization of optical binding forces, it is usable for estimation of optical forces from stochastic trajectories in general situations.Pracoviště Ústav přístrojové techniky Kontakt Martina Šillerová, sillerova@ISIBrno.Cz, Tel.: 541 514 178 Rok sběru 2023
