2014 January Lab Picture

This is the research group page of the Laser-Cooled Atoms Group at Creighton University led by Dr. Jonathan Wrubel. Our group is building an experiment to probe quantum physics in Bose-Einstein condensate of 41K (potassium-41).  This facinating state of matter is made by using lasers to cool gas atoms down to temperature below a millionth of a degree above absolute zero.  This novel state allows us to study quantum magnetism.

News

January 2015: The ECDL is locked to the saturated absorption system.

January 2014: The external cavity diode laser has its first light!  Nathan Holman (M.S. candidate) is getting it tuned to the correct wavelength.
