Laser Cooling

What Is Laser Cooling?. Proposed only 25 years ago. . Laser Cooling ? The use of light to exert forces on neutral atoms that will slow them down, thus cooling them.. Why Do We Care?. Atoms are difficult to study Transit time Blurred spectroscopy. . Cool them, slow them down, and better measuremen

    2. What Is Laser Cooling? The idea is that were going to use light and the momentum it carries to apply a damping force on atoms, slowing them down, making them colder.The idea is that were going to use light and the momentum it carries to apply a damping force on atoms, slowing them down, making them colder.
