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. In 1986 Richard K. Chang et al. demonstrated lasing using ethanol microdroplets (20–40 micrometers in radius) doped with rhodamine 6G dye. This type of optical cavity … See more 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 … See more • Optical feedback • Multiple-prism grating laser oscillator (or Multiple-prism grating laser cavity) See more 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 Fabry–Pérot cavity, consisting of two opposing flat mirrors. While simple, this arrangement is rarely used in large-scale … See more Only certain ranges of values for R1, R2, and L produce stable resonators in which periodic refocussing of the intracavity beam is produced. If the cavity is unstable, the beam size will grow without limit, eventually growing larger than the size of the cavity mirrors … See more Optical cavities can also be used as multipass optical delay lines, folding a light beam so that a long path-length may be achieved in a small space.
