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 ...
A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has detected radio recombination lines (RRLs) of ions heavier than helium for the first time, using ...
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 ...
