Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Tunable, High Pulse Energy and Narrow Linewidth Gas‐Filled Fiber Laser Across Near‐ and Mid‐Infrared

Laser &Photonics Reviews, EarlyView.
A cascaded gas‐filled anti‐resonant hollow‐core fiber architecture enables broadly tunable infrared Raman lasers spanning ∼1.4–4.6 µm while maintaining microjoule‐level pulse energies and gigahertz‐level linewidths. The approach combines a wavelength‐tunable pump laser with optimized Raman frequency conversion, providing a compact route to high ...

Side‐DBR Guided Exciton‐Polariton Lasing With Near‐Field Mode Imaging in an InGaN Thin‐Film Ridge Waveguide

Laser &Photonics Reviews, EarlyView.
Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

High‐Pressure Chemical Vapor Deposition Growth of Transition Metal Dichalcogenides With Minimized Sulfur Vacancies

National Materials, EarlyView.
High‐pressure chemical vapor deposition at 3800 torr elevates the sulfur chemical potential during MoS2 growth, suppressing sulfur‐vacancy formation. This thermodynamic control yields MoS2 with defect densities comparable to those of exfoliated crystals, enhanced crystallinity, uniform defect distribution, and improved electronic transport properties ...
