Two-Photon Transitions with Time-Delayed Radiation Pulses
1990It is known that in order to have two-photon transitions in a system interacting with two monochromatic radiation beams the sum of the photon energies has to be equal to the energy difference between the initial and final level.1 Although all states have to be taken into account as intermediate virtual states in the calculation of the transition rate ...
