Liberko Exploring Light-Matter Interactions at the Nanoscale with Synchrotron Infrared Nanospectroscopy and Spatial Modulation Spectroscopy 2023 .txt text/plain 522 23 43 Knowledge of the laser's focal parameters (such as its position and beam waist) are crucial to extracting extinction parameters. Transmitted laser intensity is measured versus blade position resulting in a sigmoidal response whose fit parameters yield the beam position and beam waist. cache/pk02c82515k.txt txt/pk02c82515k.txt
