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.

Chaos with Gaussian invariant distribution by quantum-noise random phase feedback
Optics Express, 2023 We experimentally present a random phase feedback based on quantum noise to generate a chaotic laser with Gaussian invariant distribution. The quantum noise from vacuum fluctuations is acquired by balanced homodyne detection and injected into a phase modulator to form a random phase feedback.

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.

Limited-Feedback Distributed Relay Selection for Random Spatial Wireless Networks [PDF]
2019 IEEE Global Communications Conference (GLOBECOM), 2019 This paper considers a location-based optimal relay selection scheme for a relay-assisted wireless network where available decode-and- forward relays are distributed as a homogeneous Poisson point process. To solve an optimum relay selection problem, a central entity or the source requires information pertaining to all relay locations.

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
