Key points:
- Phase matching relies on the macroscopic ensemble to perpetuate the phase, and on the microscopic quantum system to couple the interactions
- Interactions occuring in the quantum state evolution must correlate with the net polarization wavevector forming (energy and momentum conservation)
- Phase matching is spatially and temporally coherent (scales as N^2 rather than N)
- Phase mismatch can occur; attenuation due to nonlinearity of index of refraction and absorption
