The Path to Practical Attosecond Sources Is Getting Shorter Attosecond photonics allows for deep insights into material dynamics on ultrashort timescales and at nanometer resolutions. Because the attosecond is the natural timescale of electron motion within...
Editorial
Science shifts into attosecond gear Mere days before our cover story on attosecond photonics went to press, the Nobel Prize in Physics was awarded to three researchers for their pioneering accomplishments in attosecond science. My immediate response was glee that our November cover story made us appear almost prescient, until I realized that the article mentioned neither Pierre Agostini, Ferenc Krausz, nor Anne L’Huillier...

A Closer Look at Laser Protective Eyewear As distinguished readers of Photonics Spectra, you may feel as if there is little more to learn about laser protective eyewear, though certain core knowledge is worth repeating, and there may be items of which some readers are not aware. Did you know, for instance, laser protective eyewear is only required to have the same impact resistance as commercial sunglasses? There are several standards...

Lighter Side
A new twist on feeling the blues One of the most fascinating aspects of nature is how organisms evolved defense mechanisms over time. Like felines’ retractable claws or the Komodo dragon’s septic mouth, some mechanisms adopt the view that a good offense makes the best defense. Others are more reactionary, such as a lizards’ ability to detach appendages at the first sign of trouble or other creatures’ ability to blend in with...
