... When a property is quantized then the values it can adopt are limited. Every quantized property has what is known as a quantum number. In the case of the hydrogen (H) atom the quantum number which limits the allowed energies that the electron can adopt is given the symbol n, and is called the princi ...

Investigation of possible microcavity effect on lasing threshold of nonradiative-scattering-dominated semiconductor lasers
... active region does not completely fill the cavity, in which case reducing the cavity dimensions may increase Cmod; however, such lasers are excluded from this discussion. Based on this straightforward discussion, a microcavity will have no positive effect on the reduction of the pump threshold densi ...
