Optical resonators
Optical resonators are devices that trap and bounce light back and forth to amplify specific wavelengths or colors. They consist of mirrors arranged so light reflects multiple times, creating a stable optical environment. This setup enhances certain light signals, making them useful in lasers where precise, intense beams are needed. The resonator's properties determine which wavelengths are amplified, allowing control over the light's color, coherence, and intensity. In essence, optical resonators are critical components that manipulate light in advanced technology like lasers, sensors, and communication systems.
