Abstract

When electromagnetic radiation interacts with a material medium, it is treated as a radiation-matter interaction phenomenon. It is used to study the emitted electromagnetic radiation that arises from the interaction of an incident light beam with a material medium, obtaining from this the physical properties associated with it. This radiation can be absorbed or emitted because it can explain induced electronic transitions between the different energy levels of the material, with the different types of spectra generated as a result of these transitions. This is why, with the discovery of laser light, techniques emerged that allow us to study phenomena associated with the interaction of radiation with matter.That is, through this interaction, optical phenomena inherent to wave-like processes, reflection, total internal refraction, light scattering, and absorption can be studied, allowing us to understand the optical properties of the system under study. This equipment allows me to study the Einstein coefficients generated by spontaneous emission, using erbium-doped fibers. Spontaneous emission and its relationship with the probability of stimulated emission of two emitted signals are described using probabilistic data.
