Lasers Shape a New Future for Additive Manufacturing of Metal Parts
Aerospace and automotive manufacturers initially adopted additive manufacturing (AM) methods as a means to rapidly prototype new parts or to fabricate more complex or consolidated components in a single step. They applied additive manufacturing to polymers, then composites, and eventually to more challenging materials such as metals and ceramics.
Beam Profiling Evolves to Keep Lasers in Line with New Applications
Lasers provide many different industries with greater efficiency, less waste, and higher precision, but they are not always as easy to fix as the machines they replace. A blunted drill bit is easier...
Photonics Brightens the Future for Augmented Reality
Out in the Gulf of Mexico, an offshore oil rig experiences a critical mechanical failure. The engineers with the expertise to fix the problem are back on the mainland, and flying them to the site on...

The 2022 Nobel Prize in physics was awarded to three scientists, each with a record in quantum research. They were rewarded for discoveries they had made three decades ago, discoveries that paved the...
EDITORIAL
It’s the thought that counts
It is poor form to compare the largesse of the recent gift-giving season against that of past holidays. Hopefully, the rules are more forgiving when comparing scientific discoveries. As rumors mounted last month about a major breakthrough in laser fusion, there was time to contemplate how the looming announcement might stack up against the launch of the James Webb Space Telescope that had...
