       | Does nonlinear optics also create harmonics as with nonlinear
       | electronics?

         | Yes, this is how frequency-doubled lasers work (eg. 532 nm
         | green laser pointers, which are generated as a harmonic from a
         | 1064 nm Nd:YVO4 laser by a nonlinear KTP crystal).

       | This is extremely cool! Curious on the story behind this

       | It reminds me of Huygens Optics' recent videos about modelling
       | particles as confined light using a particular non-linear medium
       | [0], is it possible to create similar 'light' particles with
       | tweaks to your setup?
