A quantum system has three energy levels, so three wavelengths appear in its emission spectrum. the shortest observed wavelength

The wavelength released is inversely related to the variation in energy level change. At 278 nm, the energy level change is notably high. The wavelength of 454 nm relates to another change in energy level, although the variation from this wavelength is not as significant as the one prior. It's possible that the subsystems now exhibit very low energy, which could correspond to wavelengths between 700 and 900 nm. Additionally, there's a chance that some metastable subsystems exist within the system, which may lead to LASER emissions.
