Q-switching

Q-switching is a technique used in lasers to produce very short, intense bursts of light. In a laser, light is amplified and builds up in a cavity. Q-switching temporarily prevents that light from escaping, allowing it to accumulate. When the switch is released, all the stored energy is released at once, resulting in a powerful pulse of laser light. This process is useful in various applications, such as in laser surgery, tattoo removal, and materials processing, where concentrated energy is needed for effective results.
