Editorial
A roadblock on the roadmap Photonics Spectra’s seeming prescience is a fortunate by-product of our monthly publication schedule. The Royal Swedish Academy of Sciences’ decision to award Pierre Agostini, Ferenc Krausz, and Anne L’Huillier last year’s Nobel Prize in Physics, for example, greatly simplified the selection of our November 2023 cover story; contributing editor Marie Freebody, as if by fate, had polished off an...
Laser Safety
LED Applications Require Exposure Limits to Safeguard Consumers Many products, including some that are indispensable to modern society, experience widespread adoption before consequential health and safety risks emerge. Sometimes these adverse effects are minimal, affect a small percentage of the population, or occur only in certain unlikely circumstances. The exposure to asbestos and lead concentrations in consumer paints, for example, can result in more...
