Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis
Laser &Photonics Reviews, EarlyView.We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Bounded Frequency Lattices in Coupled Lithium Niobate Ring Cavities
Laser &Photonics Reviews, EarlyView.We leverage coupled asymmetric ring resonators in realizing bounded tight‐binding frequency lattices and demonstrate their discrete band structures on an integrated device. Suppression of long‐range coupling with a single auxiliary cavity is demonstrated by combining mode splitting and coupled waveguide dispersion effects.

Noise Suppression via Gain‐Dispersion‐Managed Nonlinear Amplification in a High‐Power Er‐Fiber Laser
Laser &Photonics Reviews, EarlyView.Gain‐dispersion‐managed nonlinear pre‐amplification simultaneously suppresses phase and intensity noise, enabling scalable high‐power fiber amplification. The system delivers 102.3 W linearly polarized pulses with 1.19 µJ energy at 85.69 MHz and compresses them to 380 fs. Near‐linear power scaling without evident saturation highlights a practical route
