Breaking the diffraction resolution limit by stimulated emission: stimulated-emission-depletion fluorescence microscopy
Stefan W. Hell,Jan Wichmann +1 more
TL;DR: A new type of scanning fluorescence microscope capable of resolving 35 nm in the far field is proposed, overcome the diffraction resolution limit by employing stimulated emission to inhibit the fluorescence process in the outer regions of the excitation point-spread function.

Upconversion and Anti-Stokes Processes with f and d Ions in Solids
TL;DR: Before the 1960s, all anti-Stokes emissions, which were known to exist, involved emission energies in excess of excitation energies by only a few kT and were linked to thermal population of energy states above excitation states by such an energy amount.
