The annual global market for laser equipment is estimated at $60 billion – with industries from manufacturing, medicine and measurement to sensing, lighting, and entertainment, all reliant on it.

Coordinated by Laserline, the consortium succeeded in writing the fiber Bragg gratings into quartz fibers with a core ...

A hybrid electroluminescence device achieves room-temperature single-photon emission, advancing quantum technologies with ...

The choice of semiconductor material is determined by its optical properties and its bandgap energy, which determines the emission wavelength. Laser diodes also have very stringent material ...

Into the orange According to the paper, laser emission at orange wavelengths (defined as 590-625 nm) is of key importance in ...

Using an infrared pulsed carbon dioxide laser, project leader Howard Milchberg and his team showed that they could detect low ...

[Les] demonstrates the power and the speed of his lasers, which can even excite laser emissions in a plain cuvette of rhodamine dye — no mirrors needed! Although eye protection is, of course.

"My group has been working on the generation of THz radiation by laser-induced filaments in air for almost 20 years," Aurélien Houard, senior author of the paper, told Phys.org.

The Laser Safety Program is managed by the Radiation Safety Office, a subset of the Office of Environmental Health and Safety (EHS). We are here to ensure that laser use on campus be conducted in a ...
