"An example of optical feedback in science is the optical cavity found in almost every laser, which typically consists of two mirrors between which light is amplified. In the late 1990s it was found that so-called unstable-cavity lasers produce light beams whose cross-section present a fractal pattern. Optical feedback in science is often closely related to video feedback, so an un… " - Optical feedback
