What is q swich?

A Q-switch is a device that is used to control the timing and frequency of laser pulses. It is called a Q-switch because it works by quickly switching the laser from a low-Q (low-energy) state to a high-Q (high-energy) state, which releases a burst of intense light. Q-switch technology is used in a variety of laser-based applications, including laser machining, tattoo removal, and medical procedures. The Q-switch is an important component in producing high-quality, high-energy laser pulses with precisely controlled characteristics.
