  Optical scattering force is used to reduce the loading time of single atoms
to a cavity mode. Releasing a cold atomic ensemble above the resonator, we
apply a push beam along the direction of gravity, offering fast atomic
transport with narrow velocity distribution. We also observe in real time that,
when the push beam is illuminated against gravity, single atoms slow down and
even turn around in the mode, through the cavity-transmission measurement. Our
method can be employed to make atom-cavity experiments more efficient.
