Nettet22. sep. 2024 · We analyze theoretically the optically induced transparency for a weak probe field in two cavity system; one linear cavity coupled to a nonlinear cavity. The nonlinear cavity contains optical Kerr medium. The two cavities are coupled via tunable photon hopping. 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 parametric … Se mer 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 suppressed by … Se mer A transparent dielectric sphere, such as a liquid droplet, also forms an interesting optical cavity. In 1986 Richard K. Chang et al. demonstrated Se mer If the optical cavity is not empty (e.g., a laser cavity which contains the gain medium), the value of L needs to be adjusted to account for the index of refraction of the … Se mer • Optical feedback • Multiple-prism grating laser oscillator (or Multiple-prism grating laser cavity) • Coupled mode theory Se mer The most common types of optical cavities consist of two facing plane (flat) or spherical mirrors. The simplest of these is the plane-parallel or Se mer Only certain ranges of values for R1, R2, and L produce stable resonators in which periodic refocussing of the intracavity beam is produced.
