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 ...

Knight Optical, the leading global supplier of on-spec, metrology-tested optics, has revealed its latest product offering – a trio of components that are suitable for a wide range of laser varieties, ...

Twisting laser patterns into a corkscrew-like pattern, rather than sending the light beams in a line, promises to relieve some data gridlock, say scientists A bottleneck in data rates is coming, some ...

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 ...
