This is extremely cool! Curious on the story behind this /u/westoncb!

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?

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).

No idea in what field/application this is useful but it's really cool and impressive nonetheless

Anyone knowledgeable in this field who could share how this can be applied?
