The energy of the photon can be worked out using the equation If an electron moves from level ... This causes line emission spectra to be produced, as shown below. This is not a continuous ...

Two-photon emission (2PE) is a process in which an electron transition between quantum levels occurs through the simultaneous emission of two photons. Two-photon emission is interesting because it ...
