After a summer and part of a fall building an experiment control system – thanks to thesis student Sierra Jubin ’17 for preliminary work – we can finally control our 4-channel DDS to drive AOMs (built by Ashay Patel ’18), collect fluorescence counts with our PMT, and send TTL pulses all over the lab.\u00a0 Our first fluorescence spectrum:<\/p>\n

The peak of the 397 nm resonance is centered at roughly 245 MHz.\u00a0 To the red side is a micromotion sideband due to a modest stray electric field.\u00a0 On the blue side we see a dip in the fluorescence due to electromagnetically induced transparency when the 397 nm laser is tuned to satisfy a two-photon resonance along with the 866 nm repump laser.<\/p>\n","protected":false},"excerpt":{"rendered":"
