If you are going to get into QM what about the double slit experiment too.

The double slit experiment is not all that simple to explain. You should check out some of the papers available on line about the results of research various people are doing with a simple device that is not at all simple. It is not at all hard to follow and it is very interesting stuff relating to a lot of topics being chatted about on this site.

Quantum light experiments are usually performed using lasers. Do you think it might be the coherent nature of the light that leads to the effects? What exactly would a coherent wave look like? Assuming a pure wave nature of light, how would a coherent beam be possible? If one is going to posit a particle medium for light would it not be necessary to be able to explain these well known effects in terms of the theory?

Emissions from every star have the property of coherence. It is just more obvious in lasers because all emitted light has the same wavelength, whereas stars emit at a spectrum of different wavelengths. For stars, the property of coherence exists because the sum of any two sine waves with a common period is another sine wave.

What makes a laser useful is that the wave fronts also propagate in the same direction and this is also required AFAIK for the waves to be considered "coherent". In any case I have never seen an explanation for how this directionality is maintained over vast distances if light is a pure wave. When the particle nature of light is assumed the explanation is trivial.
