At the dawn of the universe, there was only hydrogen and helium. These elements made up all the galaxies and all the stars. But stars fuse hydrogen and helium into heavier elements, and large stars ...
New excitation method of stimulated Raman scattering achieves natural-linewidth-limit spectral lines
The interference induces modulations on the SRL signal. A Fourier transform of the modulated SRL signal trace enables natural-linewidth-limit spectral lines. “The spectral range of T-SRS imaging is ...
The new approach produces extremely accurate and stable frequencies and could significantly enhance precision timekeeping and high-resolution atomic and molecular spectroscopy. WASHINGTON — ...
Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...
High resolution and sensitivity are critical in nuclear magnetic resonance (NMR) spectroscopy. Both can be overdoubled when using heteronuclear decoupling. This enables the severance of overlapping ...
