| Outline of Final Research Achievements |
We constructed a system for simultaneous laser cooling of rubidium, lithium, and strontium for the exploration of quantum atom optics. For the first time, we quantitatively evaluate the effect of the cooling laser of Sr on the laser-cooled Rb atoms (photo-ionization loss). We also developed a variety of methods to simplify the optical setup for laser cooling of Sr, and established a way of spectroscopy of Sr both in the ground and the excited states using a hollow-cathode lamp.
