Photonic Gas Analysis Probes Upgrades in Sources and Detectors The hunt is on for better gas analyzers, driven by growing demands. For instance, hydrogen sulfide, an industrial byproduct, has a permissible worker exposure limit of 20 ppm in a confined space, according to OSHA. Increasingly stringent emission regulations for greenhouse gases such as methane are also driving adoption. Photonics-based gas analysis employs a number of techniques and component...

Editorial
How open should AI be? Google’s strikingly simple search page first appeared the same year this editor first began working for Photonics Spectra. There was, at that time, a healthy number of people who still mistook the predigested content of America Online for the wild west of the worldwide web. More savvy internet users probed the internet’s rich information resources using a collection of search protocols labeled...
Photonic Fundamentals
Powering the Pulse: Power Design's Impact on Laser Performance Pulsed lasers have become increasingly common in manufacturing and engineering applications over the past few decades. These powerful tools enable industrial engineers to execute various materials processing tasks, such as cutting, marking, welding, cleaning, and texturizing. Lasers are often able to perform all of these tasks with more precision than waterjet, plasma, or electromechanical...
