"WebLasers are also characterized by the duration of laser emission - continuous wave or pulsed laser. A Q-Switched laser is a pulsed laser which contains a shutter-like device that does not allow emission of laser light until opened. Energy is built-up in a Q-Switched laser and released by opening the device to produce a single, intense laser pulse. " - Continuous wave vs pulse wave laser
