WebAug 18, 2024 · Incoherent cathodoluminescence emission occurs when the material is excited with an electron beam, where the primary electrons decelerate and deposit energy into the material. An important property of incoherent CL is that there is no fixed phase relation between a photon that is emitted and incoming excitation electron. This CL type … WebThe spatial coherence of light with thermal origin is also normally small, because it arises from uncoordinated (incoherent) emission from a substantial area. Higher spatial coherence can be obtained by using thermal emission from a small emitter. However, it will usually be hard to achieve a spatial coherence which is comparable to that of a ...
