Blow away beam not blowing all atoms away from F=2 state. There always seems to be some atoms there when I check that population.
In March 2014, the 50 Watt FORT laser had terrible lifetimes. There are some pictures that should be in the Z drive. Now, after buying the new FORT laser, they look much more reasonable. wtf? The one thing I did differently was put the laser through a beam cube and aligned the cavity mirrors to maximize the linearly horizontal polarized light.
