At high power, laser light inside a multimode optical fiber is supposed to misbehave. The beam usually breaks into a noisy, scattered pattern as the light ricochets through many paths at once.

We’ve all heard the “Do not stare into laser with remaining eye” joke. It’s funny because it’s true, as pretty much any laser a hobbyist can easily come by can cause permanent damage to eyes unless ...

Researchers at the U.S. Naval Research Laboratory have devised a new way to build powerful lasers that are more efficient and safer for your eyes by using nano-particles. The particles are used to ...

The inventors of an unconventional, ribbon-shaped optical fiber geometry say that it could be set to drive fiber-laser power output dramatically, while maintaining beam quality. Based at the Lawrence ...

Cladding light stripper (CLS) technology addresses a major challenge in scaling thulium fiber lasers beyond their long-standing 1 kW power limit. A new self-adapting CLS design distributes heat along ...
