Abstract Based on an improved optical system, which consists of six laser diodes with two injection locking stages and control set-ups of the intensity and frequency of the laser, we have achieved the first optical molasses in China. The time-of-flight (TOF) signal of the cloud of Cs atoms has been obtained, and an analytical-formula for measuring the temperature of the atomic cloud from its TOF signal is given. The lowest temperature of the cloud of Cs atoms is measured to be 10μK.
