We report a clock transition spectrum approach,which is used to calibrate the zero-crossing temperature and frequency drift of an ultralow expansion(ULE)cavity with a Hertz level resolution.With this approach,the line...

We report laser frequency stabilization with modulation transfer spectroscopy(MTS) on 85 Rb atoms. With both PZT(piezo-electric transducer) slow-loop feedback and current fastloop feedback to the laser head, we ge...

The laser cooling of ytterbium(Yb) atoms needs a 399-nm laser which operates on the strong1S0-1P1 transition and can be locked at the desired frequencies for different Yb isotopes.We demonstrate a frequency locking ...
