About The Position

The student will work with Argonne staff scientists, engineers, postdocs, and graduate students to design and build a fast, robust optical switching system for multiplexed, wavemeter-based laser frequency stabilization of multiple lasers. The student will use a 1D scanning galvanometer (“galvo”) to rapidly route optical signals from multiple fiber-coupled laser inputs and will implement control electronics to coordinate the galvo driver movement with the wavemeter’s measurement cycle. This laser frequency stabilization system will enable upcoming tests of fundamental symmetries using laser cooled atoms that require many frequency stabilized lasers operating simultaneously. A galvo-based switching approach will achieve robust laser stabilization without crosstalk between laser pathways due to the precise mechanical motion of the galvo motor. Deliverables will include an evaluation of the switching speed and laser feedback delay. We also expect the student’s work will contribute to an upcoming publication on improved laser cooling of neutral radium atoms.
