An oscillator-driven femtosecond pump–probe system measured local optical dynamics in multilayer and monolayer MoS₂. The reported setup combined an estimated whole-spectrum time resolution below 100 fs with submicrometre spatial resolution and found different long-lived responses at the centre and edge of one monolayer flake.

A model-based arXiv preprint examines how structured driving fields could control the geometry and geometric phases of high-harmonic optical cat states. Its results are theoretical calculations, not an experimental demonstration.

A preprint reports a numerical design in which vertical modulation controlled conversion between two modeled waveguide modes, while horizontal routing largely avoided that same transition. The simulations also show that horizontal writing-position errors can open leakage into a third mode.

A modeling study describes how a two-color ultrashort laser pulse with a changing focal velocity could shape terahertz radiation. The calculations produced a parabolic wavefront in one decelerating case and a conical, ring-shaped pattern for a constant-velocity comparison, while also showing limits at the highest tested velocity.

A preprint presents an implicit neural representation for designing three-dimensional point-spread functions. The reported tests included rotating helixes, an extended-depth-of-field pattern and multifocal designs, but the evidence is qualitative and limited to a described optical setup.

A computational study of high-harmonic generation in thin silicon slabs found that propagation depth and observation geometry changed the modeled spectrum. An alternative propagation method agreed with the full Maxwell calculation in some low-order cases but produced a model-sensitive high-order cutoff.
