In two photon XPS a laser pulse is synchronized with a pulsed x-ray source like in a single bunch synchrotron mode. The laser pulse can excite the material and change the electronic structure in a very short time domain. The correlated x-ray pulse is than used to excite a core electron in order to probe the modified electronic structure. Changing the delay time of the pulses yield useful information of the electronic mechanisms in the original and modified electronic structure.
