Random laser

A random laser is a type of laser that operates based on the principles of random scattering rather than a well-defined optical cavity. In a traditional laser, light is amplified in a highly organized manner within a coherent optical cavity formed by mirrors. The laser action occurs when a specific population of energy states is established, allowing light to be emitted in a coherent and directed beam. In contrast, a random laser does not rely on mirrors or a perfectly structured cavity.
