Q-Switch

A device that has the effect of a shutter to control the laser resonator's ability to oscillate. Control allows one to spoil the resonator's "Q-factor," keeping it low to prevent lasing action. When a high level of energy is stored, the laser can emit a very high-peak-power pulse. See Pulsing.
