the excitation of a system (an atom or molecule) from low-energy excited state to a high-energy excited state with the absorption of a photon is called "excited state absorption" (esa). excited state absorption is possible only when an electron has been already excited from the ground state to a lower excited state. the excited state absorption is usually an undesired effect, but it can be useful in upconversion pumping. the excited state absorption measurements are done using pump-probe techniques. however, it is not easy to measure them compared to ground-state absorption and in some cases complete bleaching of the ground state is required to measure excited state absorption.
