| Abstract: | Based on the interference between two photon and two photon processes, we have studied the ultrafast modulation spectroscopy(UMS) in a four level system. The possibility of using UMS in a four level system to measure the energy difference with Doppler free precision has been demonstrated. |

| Keywords: | two photon absorption time delay four wave mixing. |
