The Technique

Caption

The laser light is sent through a "resonator," which consists of two mirrors. This resonator selects specific wavelengths. A vacuum chamber containing ultra cold atoms is placed in between the two mirrors and acts as a frequency filter. As a result, the laser can be stabilized much better than with just the empty "resonator."
