A dual-beam optical trapping system is developed for confining the micro-scale
aerosol particles with sizes smaller than 10μm, operating at room temperature in the atmo-
sphere environment. Our system can easily reload aerosols and stably perform optical trapping
for more than hours. This stable levitated trapping system provides a versatile platform for the
observation of trapped particle oscillation or performing laser cooling for the cryogenic opera-
tion.
