Crystals, 2022 We report dependence of random lasing performance of directly spin-coated multicrystalline thin films of an organic–inorganic hybrid, halide perovskite CH3NH3PbBr3 (MAPbBr3), on different substrates.

Passively mode-locked semiconductor lasers and their applications [PDF]
, 2008 In this paper we present some characterizations of passively mode-locked semiconductor lasers. These lasers are multimode and they exhibit a modulation of their output power even though they are DC-biased.

Beaming random lasers with soliton control
Nature Communications, 2018 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 ...

Function optimization of diffusive nanotriangles in random lasers
AIP Advances, 2021 The random laser has the potential to be replaced with the conventional cavity laser for abundant nanophotonics applications. For this purpose, it is essential to investigate the effect of using different materials as the diffusive medium in the random ...

Internal modulation of a random fiber laser [PDF]
Optics Letters, 2013 A characterization of a modulated random mirror laser has been experimentally carried out. Unlike conventional internally modulated fiber lasers, no distortion of the modulating frequency or self-mode-locking effects were measured. The behavior of the laser using pulsed and analog modulation up to 12 GHz is shown.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Coherent transport and symmetry breaking—laser dynamics of constrained granular matter
New Journal of Physics, 2014 We present diagrammatic transport theory including self-consistent nonlinear enhancement and dissipation in the multiple scattering regime. Our model of Vollhardt–Wölfle transport of photons is fit-parameter-free and raises the claim that the results ...
