When the excited atoms relax back into their ground state, a low-intensity glow is emitted, giving the technique its name.
Similarly, vacuum fluctuations cause an excited atom to fall into its ground state.
This generates a spherical electron wave with the excited atom as the center.
If an excited atom then emits a photon spontaneously, it will be accelerated.
An excited atom can lose its energy by emitting a photon.
Often it accompanies light emission from excited atoms or molecules in the gas.
In a medium suitable for laser operation, we require these excited atoms to quickly decay to level 2.
The excited atoms can then be removed from the system, reducing the entropy.
Also, it was noted that excited atoms emit radiation with discrete frequencies.
Thus, an excited atom may have an electron in, for instance, a 5g or 6h orbital.
