Abstract: Reminiscences of the beginning of our research on the laser cooling of atomic gases are recounted, describing what motivated us to progress from atomic clocks to laser cooling. At the beginning, we pondered upon the mechanism of laser cooling, such as the cooling of atoms in red shifted diffuse light in an integrating sphere and using light frequency shifting (the A.C. Stark effect). A description of the atomic beam experimental equipment in our lab, which was used in laser cooling, is given, and some experimental results that we obtained are displayed. Finally, we summarize our experiences and lessons learnt. In looking back on our arduous beginnings, we cherish the present, and look forward to a bright future.
