Hence lasers would always be limited in size by the diffraction limit. Now, two papers in Nature demonstrate that nanoscale plasmonic cavities based on metals can indeed create lasers with optical ...

This diffraction-limited phenomenon hindered the ... divided into separate categories according to how they view the nature of the specimen — either as a collection of single molecular labels ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

The findings, published in Nature Communications ... a few billionths of a meter thick—without relying on traditional diffraction methods to retain the light within the material.

The choice between electron diffraction and XRD depends on the specific requirements of the study, such as the need for high spatial resolution, sensitivity to light elements, or the nature of the ...
