Advanced Photonics Research, Volume 7, Issue 8, August 2026.An all‐polarization‐maintaining fiber laser is presented that enables flexible dual‐wavelength pulse manipulation by simply adjusting the PM‐SMF splicing angle. Through this precise adjustment, the system achieves controllable switching between asynchronous dual‐comb pulses and synchronous bound solitons, thereby providing a highly compact and robust ...

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy
Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1387-1391, August 2026.Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm −1 precision).
