Direct Comb Laser Two-Photon Spectroscopy for Laser Stabilization

Project Details


We intend to lock Ti:sapphire comb laser directly referring to atomic transitions with merely a 6-cm Cs-Rb mixed glass cell, without bothering using a cesium clock or optical clock and free from the sensitive scheme of 1f-2f interfrometer. We also will clarify the lineshape and some other unclear transitions during comb laser-atom interaction.
