What is an Actively Q-Switched Laser?

An active Q-switch laser is a type of laser that uses an externally controlled variable attenuator, known as a Q-switch, to modulate the intracavity losses, allowing energy to build up in the laser medium and then suddenly be released, providing pulsed laser output.
