Lasing in random media

摘要: Abstract A random laser is a non-conventional whose feedback mechanism based on disorder-induced light scattering. Depending whether the supplied by scattering intensity or amplitude feedback, lasers are classified into two categories: with incoherent and coherent feedback. brief survey of presented. It followed review our recent experimental work including measurement lasing threshold, spectra, emission pattern, dynamical response, photon statistics, speckle pattern investigation relevant length scales. Large disorder leads to spatial confinement modes, that foundation for micro laser. Some theoretical models briefly introduced. The study improves understanding interplay between localization c...
