FEATURES
Quantum Cascade Lasers Shift from an Emerging to an Enabling Technology Since the unveiling of the quantum cascade laser (QCL) at Bell Labs in 1994, the technology has evolved — from being simply a cutting-edge field in pho­tonics research to being commercially available in the form of packaged lasers, QCL-powered scientific tools with control software, and robust integrated systems. These systems now support a wide range of applications in defense, materials...
Dynamic Beam Lasers Reshape Materials Processing Applications Automotive electrification is just one of the major trends redefining the requirements for high-volume materials processing in precision manufac­turing. From the need to align and connect battery...
How Single-Photon Detection Powers Countless Applications The technologies we use in our everyday activities to monitor the world around us — to develop new medicines or to produce the materials we use to build homes, offices, and factories — all rely on...
Design for Manufacturing: Understanding Asphere Tolerances Is Key The production of optical elements has changed significantly over the last two decades, mostly due to the ever-increasing demand for optical systems from end markets, including consumer products,...
Photonics Offers Clues to the Future of Forensics Spectroscopy and other photonics technologies have long been of interest in criminal forensics — the use of analytical tools and tests to reveal unseen clues during a criminal investigation. Unlike...
EDITORIAL
Spectroscopy on the spot and in the spotlight An internal debate recently arose among the editors here that revolved around whether the topic of spectroscopy deserves a feature article in every issue of Photonics Spectra. Even before this became our current editorial policy, some editors argued, spectroscopy was almost always assigned a monthly feature topic. Others trotted out old issues to demonstrate that this belief was empirically...
TECHNOLOGY NEWS
Lasers Alter Material Properties Without Producing Excess Heat Researchers at Caltech have reported success using lasers to dramatically sculpt the properties of materials without the production of excess heat, which can damage the materials. “These tools...

LASER-TEC COLLEGE PROFILE
Monroe Community College Rochester-area employers have relied on Monroe Community College (MCC) since 1963 to educate generations of students to become optical technicians. Offering stackable certificate and associate degree programs, it is the only community college to offer an Associate of Applied Science degree in optical systems technology.
LIGHTER SIDE
All that glitters ... is not biodegradable Glitter is very hard to wash off — as parents, schoolteachers, and the fiercest Diva Royale performers know. Even after the final sparkle has been completely scrubbed away, glitter particles linger in the environment as microplastics, which are defined as fragments of any type of plastic that is less than 5 mm in length. While microplastics and their environmental impact remain an emerging...
