WebBy releasing a photon of a particular amount of energy, an electron can drop into one of the lower energy levels. If it happens to drop to an intermediate level, not n=1, the it is still in an excited state (albeit a lower excited state than it previously had). It will, if conditions allow, eventually drop back to n=1. WebAmplification. The active laser medium (laser gain/amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied.
