Atomic-scale detail is now possible with photons, thanks to a cooled-down silver tip and a clever use of plasmonics.

A key feature of the instrument is that it can be calibrated using cavity ring-down spectroscopy without the requirement of changing the optical alignment. The sensitivity of the instrument is ...

Ultra-stable lasers with high-precision middle-and long-term stability are important in scientific researches. Generally, the middle- and long-term stabilities of ultra-stable laser are mainly ...

From the last decade, there has been immense interest in development of optical components. Optical components can be broadly classified into two types viz. active and passive components. These ...

We introduce and compare two powerful new techniques for headspace gas analysis above bacterial batch cultures by spectroscopy, Raman spectroscopy enhanced in an optical cavity (CERS), and ...

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have theoretically demonstrated that photons trapped inside an optical cavity carry detailed information ...
