Efficient 1054 nm Raman Random Fiber Laser
Photonics, 2023 Low–coherence laser is regarded as the key to mitigating laser–plasma instability (LPI) in laser–driven inertial confinement fusion (ICF), where LPI can decrease the laser energy coupled to the target.

Random lasing in a short Er-doped artificial Rayleigh fiber
Results in Physics, 2020 We report on random lasing observed with 5-m-long Er-doped fiber comprising an array of weak fiber Bragg gratings (FBGs) inscribed in the fiber core and uniformly distributed over the whole fiber length.

High Power, High-Order Random Raman Fiber Laser Based on Tapered Fiber
IEEE Photonics Journal, 2017 In this paper, we demonstrate a high power and high-order random Raman fiber laser based on a 1 km novel tapered fiber (TF). The core diameter of the TF gradually increases from 8 μm to 20 μm.

Network Coding and Distributed Compression over Large Networks: Some Basic Principles [PDF]
, 2012 The fields of Network Coding and Distributed Compression have focused primarily on finding the capacity for families of problems defined by either a broad class of networks topologies (e.g., directed, acyclic networks) under a narrow class of demands (e ...

Optics Express, 2022 Strong scattering random media can localize light and extend photon lifetime through multiple scattering, which offers opportunities for stabilizing random lasers. Here, we demonstrate a frequency stabilized Brillouin random laser with high coherence enabled by photon localization in random fiber grating array (RFGA). Photon trapping is realized due to

Quasi-periodic distributed feedback laser [PDF]
, 2010 Although lasers have found numerous applications, their design is often still based on the concept of a gain medium within a mirror cavity. Exceptions to this are distributed feedback lasers(1), in which feedback develops along a periodic structure, or ...

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
