Optical Resonator

An optical resonator is a device that captures and amplifies light. It typically consists of two mirrors facing each other, allowing light to bounce back and forth between them. As the light reflects, it can gain strength, producing a stable and intense beam. Optical resonators are essential in lasers, where they create coherent light used in various applications, from cutting materials to medical treatments. By tuning the distance and conditions within the resonator, specific wavelengths of light can be enhanced, enabling precise control over the emitted light's properties.
