(Left to right) Images of \(10\;\upmu\hbox {m}\), \(5\;\upmu\hbox {m}\) and \(3\;\upmu\hbox {m}\) optically trapped particles at different time points using laser power (P) = 200 mW from each optical fiber. Especially for \(3\;\upmu\hbox {m}\) particle, position fluctuations within the 1 s recording duration can be observed. Scale bar is 10 µm.
