Perovskite Random Lasers, Process and Prospects [PDF]
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.

Random Lasers as Social Processes Simulators [PDF]
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 ...

Self‐Induced Mode‐Locking in Electrically Pumped Far‐Infrared Random Lasers [PDF]
Mode locking, the self‐starting synchronous oscillation of electromagnetic modes in a laser cavity, is the primary way to generate ultrashort light pulses.

Beaming random lasers with soliton control [PDF]
Owing to their lack of a conventional cavity, random lasers typically do not emit a defined beam in a specific direction. Here, the authors combine spatial solitons and collinear pumping to achieve light-confined random lasing with a smooth output ...

Random Lasers Based on Tellurite and Germanate Glasses and Glass-Ceramics Doped with Rare-Earth Ions [PDF]
Random lasers (RLs) based on glasses and glass-ceramics doped with rare-earth ions (REI) deserve great attention because of their specific physical properties such as large thermal stability, possibility to operate at high intensities, optical wavelength

All-optical adaptive control of quantum cascade random lasers [PDF]
Tunable quantum cascade lasers can enable applications in multiple areas. Here, the authors demonstrate the adaptive control of the modes and emission spectra of quantum cascade random lasers through a spatially-tailored optical modulation of the active ...

Temporal profiles for measuring threshold of random lasers pumped by ns pulses [PDF]
The working threshold is an important parameter to assess the performance of cavity-free random lasers. Here, the temporal profile measurement is proposed as an alternative method to determine the thresholds of the surface plasmon based random lasers ...

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