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 ...

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 ...

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 ...
