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

open access: yesLaser &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 ...

Design and Fabrication of Ultrathin Metallic Phase Shifters for Visible and Near-Infrared Wavelengths

open access: yesMicromachines
The polarization state of light is critical for biological imaging, acousto-optics, bio-navigation, and many other optical applications. Phase shifters are extensively researched for their applications in optics.

Attosecond‐Stable Two‐Dimensional Spectroscopy by a Sagnac‐Based Modulating System and a Sub‐4‐fs Continuum Source

open access: yesLaser &Photonics Reviews, EarlyView.
A novel optical platform integrates a Sagnac‐based interferometer with a high‐brightness multiple‐plate continuum source to advance two‐dimensional electronic spectroscopy. The robust system delivers octave‐spanning, 3.7‐femtosecond pulses and achieves intrinsic attosecond‐level phase stability without active feedback.

Plasmon–Exciton Coupling Enhances Second‐Order Nonlinear Response in Borophene–ZnO Hybrid Structures

open access: yesLaser &Photonics Reviews, EarlyView.
Nonlinear interactions between plasmons in borophene and excitons in ZnO lead to enhanced nonlinear and incoherent cathodoluminescence, as well as coherent second harmonic generation, under electron‐beam and laser irradiations, respectively. The anisotropic response of borophene, revealed as in‐plane hyperbolic polariton propagation, acts as a control ...

Inverse Transport and Acousto-Optic Imaging [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2017
We consider the inverse problem of recovering the optical properties of a highly-scattering medium from acousto-optic measurements. Using such measurements, we show that the scattering and absorption coefficients of the radiative transport equation can be reconstructed with Lipschitz stability by means of algebraic inversion formulas.

Tunable TIRF Microscopy: Simultaneous Visualization of Intracellular Dynamics at Multiple Depths

open access: yesLaser &Photonics Reviews, EarlyView.
Total internal reflection fluorescence microscopy confines excitation to a thin layer, but only one depth at a time. Tunable TIRF removes this limit and assigns a different illumination depth to every region of the field of view, capturing vesicle transport and membrane dynamics simultaneously without moving mechanical parts.
