| Popis: |
Using frequency-chirped radiation pressure slowing, we precisely control the velocity of a pulsed CaF molecular beam down to a few m s ^–1 , compressing its velocity spread by a factor of 10 while retaining high intensity: at a velocity of 15 m s ^–1 the flux, measured 1.3 m from the source, is 7 × 10 ^5 molecules per cm ^2 per shot in a single rovibrational state. The beam is suitable for loading a magneto-optical trap or, when combined with transverse laser cooling, improving the precision of spectroscopic measurements that test fundamental physics. We compare the frequency-chirped slowing method with the more commonly used frequency-broadened slowing method. |
