Various papers put out by the Goodson group:
And from a separate group at Northwestern:
- Entangled Photon Resonance Energy Transfer in Arbitrary Media
- Suggests three orders of magnitude improvement in cross-section relative to incoherent TPA.
- In SPDC, photon pairs are generated randomly and usually accompanied by undesirable multipair emissions.
- For solid-state artificial atomic systems with radiative cascades (singled quantum emitters like quantum dots), the quantum efficiency is near unity.
- Paper is highly mathematical, and deals with resonance energy transfer (which is still interesting)
Regarding high fluence sources, quantum dots / quantum structures seem promising.
