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

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

Laser &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.

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.
