Q-switching is a technique used in laser technology to produce short, intense pulses of light. The term "Q-switch" refers to the ability to control the quality factor (Q) of the laser cavity, which affects the energy output of the laser. By manipulating the Q factor, the laser can be switched from a low-energy continuous wave mode to a high-energy pulsed mode.
