Making lasers more efficient, versatile and compact

Their inner workings reside in the realm of physics, but lasers make everyday life possible. Talking on a cell phone or googling COVID stats while your apples and oranges are scanned at the checkout counter—lasers at every ...

Flattening the curve: Nano-film enhanced supercontinuum edition

Providing light with tailored properties through ultrafast supercontinuum generation represents an active field of nonlinear science research. A German-Australian research collaboration has presented a new concept that includes ...

Image: Hubble views galaxy NGC 5728

Meet NGC 5728, a spiral galaxy around 130 million light-years from Earth. This image was acquired using Hubble's Wide Field Camera 3 (WFC3), which is extremely sensitive to visible and infrared light. Therefore, it beautifully ...

Image: Hubble snaps speedy star jets

This striking image features a relatively rare celestial phenomenon known as a Herbig-Haro object. This particular object, named HH111, was imaged by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3).

Nature of fast radio bursts clarified

By connecting two of the biggest radio telescopes in the world, astronomers have discovered that a simple binary wind cannot cause the puzzling periodicity of a fast radio burst after all. The bursts may come from a highly ...

Engineers bend light to enhance wavelength conversion

Electrical engineers from the UCLA Samueli School of Engineering have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing ...

The paradox of a free-electron laser without the laser

A new way of producing coherent light in the ultra-violet spectral region, which points the way to developing brilliant table-top X-ray sources, has been produced in research led at the University of Strathclyde.
