Q-switch A Q-switch, short for "quality switch," is a device used in laser systems to generate short, high-intensity pulses of laser light. In laser engraving, the Q-switch plays a crucial role in controlling the timing and duration of laser pulses emitted by the laser source. By rapidly switching the laser cavity between high and low Q (quality) states, the Q-switch effectively traps and accumulates laser energy within the cavity, leading to the emission of intense, short-duration laser pulses. Q-switching enables precise control over laser energy output and pulse repetition rates, making it suitable for applications such as laser marking, micromachining, and material ablation in laser engraving processes. |
