Q.
where formula_2 is the resonant frequency, formula_3 is the stored energy in the cavity, and formula_4 is the power dissipated. The optical "Q" is equal to the ratio of the resonant frequency to the bandwidth of the cavity resonance. The average lifetime of a resonant photon in the cavity is proportional to the cavity's "Q". If the "Q" factor of a laser's cavity is abruptly changed from a low value to a high one, the laser will emit a pulse of light that is much more intense than the laser's normal continuous output. This technique is known as Q-switching.
