To make a femtosecond laser using a glass substrate, the scientists start with a sheet of glass. "We want to make stable lasers, so we use glass because it has a lower thermal expansion than ...

There has been huge progress on laser pushed sails. Laser pushed sails appear to be a path to sending probes up to 20% of the speed of light when we can make 1 gram sails that are one to two meters on ...

A variety of laser-based techniques can be used to produce colorful artwork on metals. However, each approach typically requires a different type of laser and very specific settings. In a new study, ...

Laser cutting is fun. A lot of fun. You’re putting a thing into a box and firing friggin’ lasers at it to cut or etch whatever your heart desires. It’s a wonderful Venn diagram of science and fire ...

Like every American kid who grew up with Star Wars, my ears pricked up at recent stories about Chinese laser rifles. Are we going to see wars fought with laser blasters in the near future? The answer ...

James has been writing about technology for years but has loved it since the early 90s. While his main areas of expertise are maker tools -- 3D printers, vinyl cutters, paper printers, and laser ...

Is it possible to make a femtosecond laser entirely out of glass? That’s the rabbit hole that Yves Bellouard, head of EPFL’s Galatea Laboratory, went down after years of spending hours – and hours – ...
