Turbulence hierarchy in a random fibre laser [PDF]

open access: yesNature Communications, 2017
Random fibre lasers constitute a class of lasers where the optical feedback is provided by multiple scattering in a disordered system. Here, Gonzálezet al.

Random number generation with arrays of coupled quantum-dot micropillar lasers [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2021
The paper investigates the results of random number generation with arrays of coupled quantum-dot micropillar lasers. The micropillars array laser generation is modeled based on the rate equations for quantum dot lasers.

Review of Random Fiber Lasers for Optical Fiber Sensors

open access: yesSensors, 2023
A random fiber laser does not need a traditional resonant cavity and only uses the multiple scattering of disordered media to provide feedback to achieve laser output.

Angle-free random laser enabled efficient photocatalytic degradation of Rhodamine 6G molecules

open access: yesAPL Materials, 2023
Efficient photocatalytic dye degradation has been realized based on the first attempt of using a random laser. In previous studies, most photocatalytic dye degradation was conducted by using broad-angular emission lamps, light-emitting diodes, and ...

Modes of random lasers [PDF]

open access: yesAdvances in Optics and Photonics, 2010
In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, ... In random lasers, which do not have mirrors or a well-defined cavity, light is confined within the gain medium by means of multiple scattering.

Perovskite Random Lasers, Process and Prospects

open access: yesMicromachines, 2022
Random lasers (RLs) are a kind of coherent light source with optical feedback based on disorder-induced multiple scattering effects instead of a specific cavity. The unique feedback mechanism makes RLs different from conventional lasers.

Self‐Induced Mode‐Locking in Electrically Pumped Far‐Infrared Random Lasers

open access: yesAdvanced Science, 2023

A White Random Laser [PDF]

open access: yesScientific Reports, 2018
AbstractRandom laser with intrinsically uncomplicated fabrication processes, high spectral radiance, angle-free emission, and conformal onto freeform surfaces is in principle ideal for a variety of applications, ranging from lighting to identification systems. In this work, a white random laser (White-RL) with high-purity and high-stability is designed,

Waveguided nematic liquid crystal random lasers

open access: yesNanophotonics, 2021
In waveguided nematic liquid crystal random lasers (NLCRLs), we realize polarized random laser (RL) emission and discover that the waveguide effect reduces the transmission loss of the RL whose polarization is parallel to the liquid crystal molecules ...

Random Lasers as Social Processes Simulators

open access: yesEntropy, 2023
In this work, we suggest a quantum-like simulator concept to study social processes related to the solution of NP-hard problems. The simulator is based on the solaser model recently proposed by us in the framework of information cascade growth and echo ...
