摘要
We present the experimental study of modulation transfer spectroscopy of ytterbium atoms in a hollow cathode lamp.The dependences of its linewidth,slope and magnitude on the various experimental parameters are measured and fitted by the well-known theoretical expressions.The experimental results are in good agreement with the theoretical prediction.We have observed the Dicke narrowing effect by increasing the current of the hollow cathode lamp.It is also found that there are the optimal current and laser power to generate the better modulation transfer spectroscopy signal,which can be employed for locking the laser frequency to the atomic transition.
