Is there evidence of the particle nature of light in laser interaction?

Yes but its defined by its Compton/Debroglie wavelength for point-like. It isn't some little solid ball. 

The first cut at this would be the photoelectric effect.

Imagine you have metallic sphere with photo sensors around it from inside of sphere. Suck the all air from it, to have pretty good vacuum. Then use electron gun, and some source of positrons (electron's antiparticle).

Electron will annihilate with positron, in the center of sphere, creating two gamma photons. These two photons will be detected by two photo sensors .

First detection on one side of sphere, second detection exactly on the opposite side of sphere.
