Glossary Of Laser Engraving and Cut Terms [1]

Resonator A resonator is a fundamental component of a laser system that generates and amplifies coherent light through the process of optical resonance. In laser engraving, the resonator typically consists of mirrors, optical cavities, and gain media such as gases, crystals, or semiconductor materials. The resonator cavity traps and amplifies light energy, stimulating the emission of photons in a specific wavelength range corresponding to the laser's output.

Resonator designs vary depending on the type of laser technology used, such as gas lasers, solid-state lasers, or semiconductor lasers. By controlling the properties of the resonator, such as cavity length and mirror reflectivity, operators can tune laser characteristics such as output power, beam quality, and spectral purity to meet engraving requirements across different materials and applications.
