(Phys.org)—A team of researchers with the University of Burgundy in France has shown that solitons can vibrate like real molecules when paired. They have published a paper describing their technique and findings in the ...
How can the color of laser light be changed? One popular method to achieve this is the so-called second harmonic generation (SHG) effect, which doubles the frequency of light and hence changes its color. However, observing ...
