Researchers develop ultraefficient white light laser on a chip

A team of researchers from the University of Twente has made a breakthrough in ultraefficient on-chip supercontinuum generation. The findings, published in the journal Advanced Photonics Research, represent a major step forward ...

Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

Solving a crystal's structure when you've only got powder

Crystals reveal the hidden geometry of molecules to the naked eye. Scientists use crystals to figure out the atomic structure of new materials, but many can't be grown large enough. Now, a team of researchers report a new ...

New holographic camera sees the unseen with high precision

Northwestern University researchers have invented a new high-resolution camera that can see the unseen—including around corners and through scattering media, such as skin, fog or potentially even the human skull.

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 ...

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.

Quantum leap: how we discovered a new way to create a hologram

Once, holograms were just a scientific curiosity. But thanks to the rapid development of lasers, they have gradually moved center stage, appearing on the security imagery for credit cards and bank notes, in science fiction ...
