FEATURES

High Laser-Induced-Damage Threshold Optics

Despite nearly 50 years of study, laser damage continues to be a topic of some confusion for both optics manufacturers and consumers. Laser optics purchasers need to know the primary causes of damage and the steps that fabricators typically take to minimize them. They must engage in a meaningful dialogue with potential vendors to understand what questions to ask when qualifying a supplier. ...

Analyzing Particles to Save the Planet – and for Profit

EDITORIAL

Stoking the star-maker machinery They’re making stars in Chile, Huck, and it did take a long time – about 10 years – but overnight on Jan. 21-22, there were five new stars in the Southern sky. You wouldn’t have been able to see them with your eyes, but they were there. Forgive me for mixing my cultural references, but with apologies to Joni Mitchell and Mark Twain, their words just seem to fit. The team...

Smooth flakes of gold build better plasmonic devices

Size is everything when it comes to fabricating plasmonic structures. For optical nanoantennas, for example, we’re talking about tens of nanometers in length, with a gap of less than 10 nm. At this scale, even slight defects can become a massive problem. A new nanofabrication method developed by researchers at the University of Würzburg could provide solutions for building...
