Abstract Based on the realization of magneto-optical trap for cesium atom in China, great improvement is achieved on its performance. In the new experimental setup, a laser battery in stepwise injection-locking scheme is developed as laser source, which has more output power and better beam quality than the previous one. Under the optimum working condition, cesium atoms of more than l09 with the density of 1011 atoms/cm3 are trapped to form an atomic cloud with the diameter of 3mm. Compared with previous results, both the number of trapped atoms and the density of atomic cloud are increased in two orders of magnitude.
