Lesson Flashcards: Spontaneous and Stimulated Emission Physics

Excited state lifetime

The time interval in which an electron remains in an excited state before returning to a lower energy level

Ground state electron

A bound electron that is in the lowest energy state of an atom

Excited state electron

A bound electron that has had energy transferred to it to move it to a higher energy level

Spontaneous decay

An electron in an excited state returning to a lower energy level

Spontaneous emission

The emission of a photon by an excited state electron due to the electron returning to a lower energy level

Stimulated emission

The emission of a photon by an excited state electron due to the electron absorbing the energy of a photon
