Localization of Atomic Excitation

Two main parts for the project. The coupling and probe beams for the EIT, and the FORT to trap atoms.

1064 FORT

Trying to use two 1064 lasers to trap atoms. The first is a high power, up to 10 Watts, multimode beam that initially traps the atoms. The second is a lower power, but single mode beam that can be used for evaporative cooling.

Never really got the two laser FORT set up to work. I found out that the large FORT alone can cool the atoms enough. The atoms are cooled to about 1 uk, giving them an average velocity of around 15 nm/uw. This velocity was measured with a time of flight experiment.

EIT beams

The coupling and probe beams are created from the the same seed laser, and high frequency AOM's shift the seed laser by 6.8 GHz.
