A good rifle scope maintains optical clarity, minimizes parallax, is non-reflective and is resistant to moisture, dirt and mechanical shock. These scopes must also be suitable in a wide variety of ...

Physicists in Germany have generated what they call a "special" state of matter, using a three-dimensional optical interference pattern. Turning up the intensity of this pattern created a gaseous ...

By carefully choosing the orientation of the crystal, they were able to produce stable microcombs on the chip. In their latest work, they generated a special kind called a normal dispersion Kerr ...

The laser module is one of the least reliable components in such a system. For that reason, it remains in a convenient pluggable form, enabling easy and inexpensive replacement. If designers were to ...

Nonlinear optical frequency conversion is an important enabling technology for a variety of applications, especially laser spectroscopy. Molecular spectroscopy experiments typically require light in ...

Erasable electric fields written by laser light onto crystal surfaces can trap, align, and release living cells without ...

The Nobel Prize in Chemistry 2014 was awarded for the development of super-resolved fluorescence microscopy. Inspired by this work, scientists at Institute of Photonic Chips (IPC), University of ...
