Cesium atom 6S-6D spectrum is significant for setting up suitable sets of bases for constructing wavefunction via B-Spline. Two-photon transition induced transparency with 6D1/26D3/2 transitions benefits, comparing with that performed by one-photon transition, for free AC stark shift and free power broadening, which is very promising for building up a novel secondary time standard.This project proposes to build up an 855-nm cesium-stabilized diode laser and a cesium MOT system to observe the quantum interference between two pathways of cesium two-photon transition, namely, 6D1/2, F=36D3/2, F=5 and 6D1/2, F=46D3/2, F=5.
