A laser micromanipulation is suitable for manipulation of a microscopic object suspended in the liquid. Here we proposed the synchronized laser micromanipulation (SLM) for the trajectory control of the multiple targets with each designed trajectories independently by the single laser. SLM is different from the existing laser scanning micromanipulation in that we can manipulate multiple targets independently by the single laser by changing discrete laser scanning pattern. Here we show the condition for stable transportation of targets depends on the effect of Brownian motion. Accordingly we can manipulate multiple microbeads stably along with each designed trajectories by the proposed method.
