Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...
A new atom camera uses one ultracold rubidium atom to map light intensity and polarization with spatial resolution below 100 nanometers.
This article explores LIG’s SMAL lenses, including their design principles, manufacturing methods, and performance in ...
Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...
Microspheres placed on a specimen in an interference microscope setup enable topographic measurements of structures below the physical resolution limit. Credit: Journal of Optical Microsystems (2022).
