Channeling atoms can be used to produce deposited nano-structure of high quality in laser-focused atomic deposition which is one of the technologies of laser manipulating atoms. We deduce the analytic solutions of atom equation of motion in the second approximation of Gauss function form. Through calculation simulation and analytic comparison, it is shown that there are many advantages in laser-focused atomic deposition when channeling atoms are used. These advantages demonstrate that atoms channeling is the content of complement in technology of laser-focused atomic deposition.
