Total internal reflection of a violet laser in a pane of glass. The beam appears yellow due to its wavelength being short enough to cause fluorescence in the glass, and would be invisible if it werent for this.

A thought, they call it “total” internal reflection, but theres very obviously some light leaking each time it bounces (zoom in)
A violet laser would still be visible. Perhaps you meant Ultraviolet?
Fun fact: companies deploying blue laser for 3D scanning usually avoid purple to limit UV amount and make it safer for the users.
Btw, beautiful picture.
