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.
