strontium atomic clock lasers
2014/3/18
Heralding a new age of terrific timekeeping, a research group at JILA—a joint institute of the University of Colorado Boulder and the National Institute of Standards and Technology—has unveiled an exp...
Tackling the blackbody shift in a strontium optical lattice clock
blackbody shift strontium optical lattice clock
2010/10/26
A major obstacle for optical clocks is the frequency shift due to black body radiation. We discuss how one can tackle this problem in an optical lattice clock; in our case 87Sr: firstly, by a measurem...

Oxygen Ion Implantation in Strontium Bismuth Tantalate Thin Films
Ferroelectric Thin films SBT Oxygen implantation Plasma focus
2010/9/29
Strontium Bismuth Tantalate (SBT) ferroelectric thin films have attracted considerable attention for the development of non-volatile ferroelectric random access memories (NV-FRAMs). These films, howev...
Intensity Dependence for Trap Loss Rate in a Magneto-Optical Trap of Strontium
Intensity Dependence Trap Loss Rate a Magneto-Optical Trap of Strontium
2010/10/26
We have measured the collisional loss rate for cold strontium atoms held in a magneto-optical trap as a function of light intensity in the regime of low intensity (2¡6 mW/cm2). The results confi...
