Random fiber lasers: Application to fiber optic sensors networks [PDF]
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017 Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities presented in that fiber.
