Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.The efficiency of bulk perovskite‐sensitised upconversion is hindered by parasitic singlet back‐transfer. A 2D perovskite spacer layer is introduced to weaken this loss pathway by increasing the separation between the sensitiser and the emitter. The spacer layer enhances the upconversion efficiency at lower excitation powers and improves the stability ...

Advanced Science, Volume 13, Issue 7, 3 February 2026.This study presents a femtosecond laser‐based ultrashort pulse dicing system that uses a non‐diffracting Bessel beam to shape the femtosecond laser. The use of femtosecond Bessel beam shaping and high‐speed scanning enables rapid material removal that outpaces thermal diffusion, thereby suppressing melting, minimizing the HAZ, and reducing sidewall ...

Ultrafast Laser‐Induced Interatomic Forces in Magnetostrictive Metals
Advanced Science, Volume 13, Issue 8, 9 February 2026.This study reports ultrafast changes in the interatomic forces generated by femtosecond laser excitation in magnetostrictive FeGa thin films. This ultrafast process manifests as an optical birefringence signal lasting ≈400 fs. Using a pump‐probe system, the femtosecond evolution of this nonequilibrium interatomic interaction is visualized, providing ...

Anomalous Magnetization Dynamics After Dual Optical Excitation
Advanced Physics Research, Volume 5, Issue 2, February 2026.We demonstrate that dual‐pump femtosecond excitation in copper leads to a pronounced, non‐additive change in spin and orbital relaxation dynamics compared to single‐pulse excitation. Time‐resolved magneto‐optical Kerr effect measurements reveal a 2.5× increase in angular momentum decay time, highlighting a new route to ultrafast control of electronic ...

Nanophotonics, Volume 15, Issue 3, 12 February 2026.Chirped rephasing pulses satisfying adiabatic conditions enable robust adiabatic rapid passage across a THz‐broadened InAs quantum dot ensemble. This approach provides uniform population inversion and broadband rephasing, overcoming the limitations of transform‐limited excitation.
