Ramping Up with High-Intensity Lasers In Europe, China, and the U.S., laser projects — either built or planned — are ramping up intensity, with systems now reaching peak power of 10 petawatts (PW), or 10 million billion watts. On the drawing boards are lasers that will crack 100 PW peak power, which is high enough to create matter and antimatter from empty space. Proving Einstein’s famous theory E = mc2 with lasers...
Lidar Design Optimization with Advanced Optical Resins Designing new automotive lidar systems is a complex process, made easier with access to finite element method simulation software and materials data. One of the key simulations performed is time of...

Editorial
Excelsior On a recent “stay-at-home” afternoon, my daughter and I stood in the kitchen eating lunch. We were laughing when suddenly she stopped and said, “You know, the minute I start feeling good, something happens and I realize all the people dying on ventilators, and then I feel guilty that my life is OK.” We live in upstate New York and — politics aside — tune in...

Butterfly Wing Nanostructures Achieve Ultrablack Coloration A team at Duke University is studying butterflies with wings that are 10 to 100 times darker than everyday black objects. As little as 0.06% of the light that hits the ultrablack butterfly wings is reflected back to the eye. This percentage is close to the blackest black coatings made by humans to help solar panels absorb more energy or enable line telescopes to reduce stray light. The...
