... Figure 4 shows the lasing spectrum as a function of drive current along with the corresponding L-I curve. It can be seen that as the device heats with larger current injection, the lasing mode moves to longer wavelengths due to the thermo-optic effect in the cavity. When the mode moves far enough fr ...

Although for the |ei ≡ 3 P0 atom, the decoupling is slightly broken by the admixture with higher-lying P states with J 6= 0, this admixture is very small1 and the resulting nuclear-spin-dependent variation of the scattering lengths is also expected to be very small, of ...

The absorption and scattering lead to attenuation of the initial radiation. The absorption removes radian ...

Population inversion

In science, specifically statistical mechanics, a population inversion occurs while a system (such as a group of atoms or molecules) exists in a state with more members in an excited state than in lower energy states. It is called an ""inversion"" because in many familiar and commonly encountered physical systems, this is not possible. The concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a standard laser.
