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 ...

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing
Laser &Photonics Reviews, EarlyView.Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Transient Laser‐Induced Periodic Surface Structures Revealed by Time‐Resolved EUV Diffuse Scattering
Laser &Photonics Reviews, EarlyView.The study shows that femtosecond laser pulses generate transient, LIPSS‐like surface patterns at fluences far below the damage threshold. Time‐resolved extreme ultraviolet scattering captures reciprocal space features that form within a few picoseconds and vanish on sub‐nanosecond timescales.

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
