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 …

Scattering of light by disordered structures is a common phenomenon in our daily life. For
many scientific applications, scattering is often treated as a detrimental effect. However …

Turbulence is a challenging feature common to a wide range of complex phenomena.
Random fibre lasers are a special class of lasers in which the feedback arises from multiple …

Face masks provide effective, easy-to-use, and low-cost protection against airborne
pathogens or infectious agents, including SARS-CoV-2. Existing masks are all passive in …

In this review article, we describe the basic principles of random laser operation with
particular emphasis on π‐conjugated, dye‐doped and biologically inspired polymers …

The research topic of air lasing is of fundamental and practical importance, which has grown
rapidly in the past decade. Air lasing, or a laser‐like emission from air species including …

Here, we investigate the mechanism of a random-lasing-based sensor which shows p H
sensitivity exceeding by 2 orders of magnitude that of a conventional fluorescence sensor …

Spontaneous Raman scattering is a powerful tool for chemical sensing and imaging but
suffers from a weak signal. In this Letter, we present an application of adaptive optics to …

The applications of random laser (RL) are still restricted, due to its complexity, high lasing
threshold, unstable nature, difficulty in tuning and modulating its light emission …

Random lasers (RLs) based on neodymium ions (Nd3+) doped crystalline powders rely on
multiple light scattering to sustain laser oscillation. Although Stokes and anti-Stokes Nd3+ …
