Recent advances and applications of random lasers and random fiber lasers
Progress in Quantum Electronics, 2021Abstract Random Lasers (RLs) and Random Fiber Lasers (RFLs) have been the subject of intense research since their first experimental demonstration in 1994 and 2007, respectively. These low coherence light sources rely on multiple scattering of light to provide optical feedback in a medium combining a properly excited gain material and a scattering ...

One essential component of a laser is the cavity, which provides optical confinement and feedback for lasing oscillation. In a highly disordered medium, light experiences multiple scattering and undergoes a random walk. Surprisingly, lasing can occur in a random system without well-defined cavities.

Lasers with Random Stack Mirrors
Applied Optics, 1970The behavior of Q-switched, free-running, and mode-locked laser oscillators, with one cavity mirror consisting of a stack of thin glass plates, is described. The beam divergence can equal that obtained with a thin film coated dielectric mirror, but intensity and spatial coherence vary over the beam cross section.

THEORY OF A RANDOM FIBER LASER
Журнал Экспериментальной и Теоретической Физики, 2014We develop the theory explaining the role of nonlinearity in generation of radiation in a fiber laser that is pumped by external light. The pumping energy is converted into the generating signal due to the Raman scattering supplying an effective gain for the signal.

The physics and applications of random lasers
Nature Physics, 2008Recent developments in the field of micro and nanophotonics have shown that it is possible to make use of the intrinsic disorder in photonic materials to create useful optical structures. An example is that of a random laser, in which laser action is obtained in disordered structures such as powders and porous glasses. Although these materials are easy
