WebThe cavity is defined by two mirrors. One is partially reflecting and allows the output beam to escape. The simplest cavity is defined by two mirrors facing each other — a total reflector and a partial reflector whose reflectance can vary between 30% and close to 100%. An optical cavity, resonating cavity or optical resonator is an arrangement of mirrors or other optical elements that forms a cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical … See more Light confined in a resonator will reflect multiple times from the mirrors, and due to the effects of interference, only certain patterns and frequencies of radiation will be sustained by the resonator, with the others being … See more A transparent dielectric sphere, such as a liquid droplet, also forms an interesting optical cavity.
