Origin of Thermal Nonlinear Refraction in Alcohols Revealed by Spatial Self-Phase Modulation under Excitation at 1560 nm

Abstract We investigated the relationship between molecular structure and nonlinear thermal responses of alcohols with different numbers of carbon atoms in their main chains using spatial self-phase modulation experiments at 1560 nm. The studied materials included the following a...

Absolute Primary Nanothermometry Using Individual Stark Sublevels of Rare-Earth-Doped Crystals

Abstract We present two independent optical methods for absolute primary thermometry using rare-earth-doped nanoparticles. Both approaches rely exclusively on the internal energy levels and population dynamics of the dopant ions, eliminating the need for external temperature refe...
