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 ...

Advanced Science, Volume 13, Issue 44, 7 August 2026.A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...
