Strontium MOT


Strontium Magneto Optical Trap

This setup would form the essential part of the Atom+Plasmon coupling studies. The long-lived metastable states in Sr would enable coherent manipulation of the atomic state for Quantum information studies. As a part of the construction of this setup, the group has been indigenously developing a variety of technology. We have successfully constructed a frequency doubling system for generating 461 nm from a 922 nm laser light source with an efficiency of over 30%. We have also designed and built a variety of Data-acquisition and control systems to replace expensive and imported systems. A compact Atomic beam source of Sr has been constructed and preliminary spectroscopic signals of various Sr atoms have been obtained. This spectroscopy system will be useful in stabilizing the laser for cooling of Sr atoms.
