Intuitively, it would appear the more photons the better effect.

Would not coherence be a factor? That is, just crossing any two
laser beams would not have an additive effect, even if they were
the same wavelength. I would think the electric fields would have
to be in phase.

And even so, this self lensing implies it occurs over the length
of the lights travel through the medium. Where two beams cross,
there's not a lot of medium, as opposed to, say, a single beam
traveling for several meters through something.

Just my amateur 2 cents.

Entanglement was first demonstrated in pairs of particles such as photons, but more recently physicists have also been able to entangle much larger entities such as laser beams, which contain many photons. ...
