The concept of random lasers exploiting multiple scattering of photons in an amplifying
disordered medium in order to generate coherent light without a traditional laser resonator …

In a random laser (RL), optical feedback arises from multiple scattering instead of
conventional mirrors. RLs generate a laser-like emission, and meanwhile take advantage of …

Anticounterfeiting labels based on physical unclonable functions (PUFs) exhibit high
security with unreplicable code outputs, making them an ideal platform to realize …

Random lasers (RLs) are a particular class of optical devices. In a random laser, the optical
feedback is provided by scattering media rather than by an optical cavity, as for traditional …

Random lasers are resonator-less light sources where feedback stems from recurrent
scattering at the expense of spatial profile and directionality. Suitably-doped nematic liquid …

Multicolor random lasing has broad potential applications in the fields of imaging, sensing,
and optoelectronics. Here, silver nanoflowers (Ag NF) with abundant nanogaps are …

We demonstrate an experimental technique that allows to achieve a robust control on the
emission spectrum of a micro random laser and to select individual modes with sub …

Line width-tunable lasers have wide applications in the fields of high-resolution
spectroscopy, optical communications, and other industry and scientific research. Here …

In this research, we present results of simulated annealing (SA), a heuristic optimization
algorithm, for focusing light through a turbid medium. Performance of the algorithm on phase …

The properties of quasi-random and random photonic systems have been extensively
studied over the last two decades, but recent technological advances have opened new …
