Recent advances and applications of random lasers and random fiber lasers

Progress in Quantum Electronics, 2021
Abstract 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 ...

Dissolvable and Recyclable Random Lasers

ACS Nano, 2017
An integrated random laser based on green materials with dissolubility and recyclability is created and demonstrated. The dissolvable and recyclable random laser (DRRL) can be dissolved in water, accompanying the decay of emission intensity and the increment in lasing threshold.

Random Lasers

2022
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, 1970
The 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.

PARTIALLY PUMPED RANDOM LASERS

International Journal of Modern Physics B, 2014
Conventional lasers consist of two components: a gain material that is pumped in order to provide amplification of light and a cavity to provide feedback. Random lasers replace the traditional laser cavity with a random, multiple-scattering medium. This can give rise to complex lasing behavior, such as unpredictable multidirectional and multifrequency

The physics and applications of random lasers

Nature Physics, 2008
Recent 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
