Glossary Of Laser Engraving and Cut Terms [2]

Q
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.

Quality Assurance (QA) Quality assurance is a systematic approach employed in laser engraving to ensure that products meet predefined standards of quality, reliability, and performance. In laser engraving, quality assurance involves implementing processes, procedures, and methodologies to prevent defects, identify areas for improvement, and verify compliance with engraving specifications.
Quality assurance activities may include product inspections, process audits, equipment calibrations, and employee training to uphold consistency and precision in engraving outputs. By emphasizing quality assurance, laser engraving facilities can enhance customer satisfaction, reduce rework and waste, and build a reputation for delivering high-quality engraved products.
