Spatially masked optical Kerr effect (SM-OKE) spectroscopy is a nonresonant femtosecond pump–probe technique capable of measuring isotropic contributions to the transient birefringence of molecular ...

A compact anisotropic laser-feedback polarimetry setup enables self-calibrating, dual-parameter birefringence measurement. The system retrieves phase retardance and fast-axis azimuth simultaneously, ...

Optical pump-probe setup and the layered structure of PtTe2. All-optical generation and detection of coherent phonons and helicity-dependent COP. a The inverse of COP lifetime ( op-1). b The full ...

The optical, electrical and mechanical properties of some materials change depending on the direction or orientation of the material. Depending on how wood is cut, for example, the orientation of the ...

Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional ...

Anisotropic nanoparticles are nanoparticles that possess different properties along different axes. Unlike their isotropic counterparts, which have uniform properties in all directions, anisotropic ...

Isotropic nanoparticles are nanoscale particles that exhibit uniform physical properties in all directions. Unlike anisotropic nanoparticles, which have direction-dependent properties, isotropic ...
