“…It is proportional to p at low pressures when the mean free path of air molecules is much larger than the size of the particle. A larger size in one direction will lead to a smaller damping rate of the CoM motion along that direction [26,36]. Therefore, we can estimate the shape of the nanoparticle via the measured damping rates.…”

“…The frequency of one beam is shifted by a mount of 110 MHz using an acoustooptic modulator (AOM), and then it is combined with the other laser beam (the frequency is not shifted) on a PBS to avoid the interference of the two trapping beams. Then the two beams are tightly focused by a high NA objective lens (Nikon CF Plan 100X, NA=0.95) in the vacuum system [53,54]. The directivity of one beam is precisely controlled by a motor-driving mirror.…”
