Abstract:

Narrow UV transitions in atomic Hg can be utilized for a high quality atomic frequency standard. The primary goal of the research supported by this grant was the development of a laser-cooled source of ultracold Hg atoms and the spectroscopic study of the doubly-forbidden clock transition to better understand its potential as a future atomic clock. During this funding period a novel UV laser system was developed to efficiently cool and trap atomic Hg to temperatures below 100 micro Kelvin. The narrow 1S0 to 3P0 clock transition was measured and used to determine the temperature of the Hg ensemble. The grant supported the PhD research of two students
