Webpopulation inversion, in physics, the redistribution of atomic energy levels that takes place in a system so that laser or maser action can occur. Normally, a system of atoms is in temperature equilibrium and there are always more atoms in low energy states than in higher ones. Although absorption and emission of energy is a continuous process, the …

WebLasers - Population Inversion. Under normal circumstances, the higher an energy level is, the less it is populated by thermal energy. Under some circumstances (for example, the presence of an upper energy level that has a relatively long lifetime), a system can be constructed so that there are more atoms/molecules in an upper energy level than ... 居量反轉(英語:Population inversion),又譯為群數反轉、密數反轉、集居数反轉、粒子數反轉、反轉分布,為一個物理學名詞,在統計力學中經常被使用。居量反轉即在一個系統(例如一群原子或分子)中,處在激發狀態的成員數量比起處於較低能階狀態的成員更多。讓標準雷射進入能夠運作的狀態的過程中,產生居量反轉是一個必要的步驟,因此在雷射科學中,居量反轉是很重要的研究主題之一。值得注意的是居量反轉不可能是熱平衡的穩態解,如二能階系統中,溫度極高 … howard gant obituary
