We present a new laser setup suited for high precision spectroscopy on atomic strontium. The source is used for an absolute frequency measurement of the visible 5s21S0-5s5p3P1 intercombination line of strontium which is considered a possible candidate for a future optical frequency standard. The optical frequency is measured with an optical comb generator referenced to the SI through a GPS signal. We developed also an all solid state blue laser source that will be used for laser cooling of strontium, which will result in a better control on the systematic effects and a great improvement in the precision of the measurement.

Abstract
We present a new laser setup suited for high precision spectroscopy on atomic strontium. The source is used for an absolute frequency measurement of the visible 5s21S0-5s5p3P1 intercombination line of strontium which is considered a possible candidate for a future optical frequency standard. The optical frequency is measured with an optical comb generator referenced to the SI through a GPS signal. We developed also an all solid state blue laser source that will be used for laser cooling of strontium, which will result in a better control on the systematic effects and a great improvement in the precision of the measurement.File | Dimensione | Formato | |
