What to know about 3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times

Researchers at Lawrence Livermore National Laboratory have developed a method to 3D-print all-ceramic waveguides using direct ink writing. This new crystalline architecture aims to provide higher power output and better heat dissipation than traditional silica glass fibers for use in national defense and industrial machining.

What happened

3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times Gaby Clark Scientific Editor Robert Egan Senior Editor At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world.

Why it matters

Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous distances.

Common ground

Waveguiding optics are among the most important advances in photonics since the invention of the laser.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
