New semiconductor laser delivers high power at a single frequency. As for applications, the researchers say the new all-electric organic semiconductor lasers would be straightforward to integrate into ...

A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light ...

This significant step forward in the development of photonic power converters – devices that turn laser light into electrical ...

Researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses.

The new topological insulator laser is more efficient than its conventional counterpart — that is, the intensity of the laser beam is stronger for how much power it consumes. M.A. Bandres et al ...

From smart grids to the internet of things, the modern world is increasingly reliant on connectivity between electronic devices. Thanks to University of Ottawa researchers, these devices can now be ...

Twisted light could also find use in quantum computing and quantum communications. In a beam of light with orbital angular momentum (OAM), the wavefront of the light’s electric and magnetic fields ...

Scientists have shown that laser light, under certain conditions, can behave like an object and cast a shadow. Margherita Bassi Published November 18, 2024 Latest news ...

The TEA laser pumps nitrogen to population-inversion levels, and when the N2 molecules fall back to ground state, they fling out photons at 337.1 nanometers wavelength, which is ultraviolet light ...

Scientists from Seoul, South Korea, have figured out how to transmit 400 milliwatts (mW) of electricity over nearly 100 feet using infrared laser light, according to research published in the ...
