Femtosecond Lasers Provide a Gentler Way to Micromachine
From the unbreakably hard to the vulnerably soft – from glass, metals and ceramics to plastics and biological tissue – femtosecond lasers are being increasingly adopted for micromachining a range of materials. Femtosecond lasers are cropping up in a large number of places, and their applications are surprisingly diverse. Thanks to intense yet precise energy delivery,...

QCL Spectrometer Detects Hazardous Materials
A new MEMS-based spectrometer that operates in the mid-infrared could form the basis of a handheld system for detecting hazardous materials. Developed at the Fraunhofer Institute for Photonic Microsystems (IPMS), the device incorporates a 5-mm diffraction grating controlled by microelectromechanical systems (MEMS). It works with a quantum cascade laser (QCL) — under development by...

Data For The Masses
Hindsight is 20/20. In February of 1995, Newsweek published an article titled “The Internet? Bah!” wherein the author deemed the hype surrounding an online future to be a large helping of “baloney.” Twenty years later, fiber optic cables buried in the ocean floor carry over 99 percent of that so-called drivel to millions of people – who rely upon the data like never...
