so the photon as linear momentum(P=E/c),spin(intrinsic angular momentum),and now we find out it has orbital angular momentum. Is there any other momenta associated with a photon?
What does intrinsic mean anyway?

Where are you guys getting the idea that we didn't know that light has orbital angular momentum?

Instrinsic means that it is a fundmanetal property of the photon, i.e. all photons have a spin quantum number(s) of 1 which is related to the spin angular momentum by:
As far as I'm aware, there are no other sorts of angular momentum other than those described associated with the photon (excpet for things like total angualr momentum which is the sum of spin and orbital angular momentum).
does not seem to have any assymmetry that would decide the direction of twist. What then determines whether the helical wavefront is right or left handed?
If we calculate the interference pattern generated by combining LG00 and LG0+1...
