A first for a unique instrument

Geophysicists at Ludwig-Maximilians Universitaet (LMU) in Munich have measured Earth's spin and axis orientation with a novel ring laser, and provided the most precise determination of these parameters yet achieved by a ground-based ...

Molecular vibrations lead to high performance laser

Lasers. They are used for everything from entertaining our cats to encrypting our communications. Unfortunately, lasers can be energy intensive and many are made using toxic materials like arsenic and gallium. To make lasers ...

Running light around a tetrahedron

Thanks to an innovative ring laser design, geophysicists at LMU can now measure and monitor Earth's rotation with unprecedented accuracy. The new instrument in F├╝rstenfeldbruck will be formally inaugurated this week.

'Going deep' to measure Earth's rotational effects

Researchers in Italy hope to measure Earth's rotation using a laser-based gyroscope housed deep underground, with enough experimental precision to reveal measurable effects of Einstein's general theory of relativity. The ...

Uniquely shaped enzyme amazes chemists

Chemists of Radboud University Nijmegen have found that a uniquely shaped enzyme that has never been seen before in biology is real: two interlocked ring structures, known as catenanes . The results have been published early ...

First ever direct measurement of the Earth's rotation

A group with researchers of the Technical University of Munich, Germany, are the first to plot changes in the Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. ...

Tapering a Free-Electron Laser to Extract More Juice

(PhysOrg.com) -- Researchers from the NSLS and Science Applications International Corporation (SAIC) have demonstrated a technique that could be used to significantly improve the quantity and quality of light produced from ...
