We investigate how entanglement can enhance two-photon absorption in a three-level system. First, we employ the Schmidt decomposition to determine the entanglement properties of the optimal two-photon state to drive such a transition, and the maximum enhancement which can be achieved in comparison to the optimal classical pulse. We then adapt the optimization problem to realistic experimental constraints, where photon pairs from a down-conversion source are manipulated by local operations such as spatial light modulators. We derive optimal pulse shaping functions to enhance the absorption efficiency, and compare the maximal enhancement achievable by entanglement to the yield of optimally shaped, separable pulses.

The two-photon absorption process was used to obtain the first observation of particle precipitation in liquids between halogen-containing organic compounds and silver-containing inorganic compounds. Photo-detachment of an electron from negative ions was found to be one important mechanism that led to these chemical reactions. Similar processes may lead to many new multiphoton-induced chemical reactions between organic and inorganic compounds.

The cubic hyperpolarizabilities of 1,3,5-(trans-[RuCl(dppe)2(C≡CC6H4-4-C≡C)])3C6H3 (1), 1,3,5-(trans-[Ru(C≡CPh)(dppe)2(C≡CC6H4-4-C≡C)])3C6H3 (2), 1,3,5-(trans-[Ru(C≡CC6H4-4-NO2)(dppe)2(C≡CC6H4-4-C≡C)])3C6H3 (3), 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CPh)(dppe)2(C≡CC6H4-4-C≡C)])2C6H3)(dppe)2(C≡CC6H4-4-C≡C)]}3C6H3 (4), and 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CC6H4-4-NO2)(dppe)2(C≡CC6H4-4-C≡C)])2C6H3)(dppe)2(C≡CC6H4-4-C≡C)]}3C6H3 (5) have been assessed over the spectral range 520–1600 nm using the Z-scan technique and ~150 fs pulses. All complexes exhibit negative values of γreal (corresponding to self-defocusing behaviour) and significant positive values of γimag (corresponding to two-photon absorption) at short wavelengths (up to 1000 nm). The maximal values of γreal and γimag increase in magnitude on dendrimer generation increase (proceeding from 2 to 4 or 3 to 5). The open-aperture Z-scan results have been used to confirm and contrast the two-photon (2PA) and three-photon absorption (3PA) behaviour of 1–5, the data being consistent with the existence of 2PA at the short wavelength range, but with significant 3PA at longer wavelengths for 1–3 and 5, a record 3PA coefficient for an inorganic complex for 5 at 1180 nm, and appreciable 3PA at the telecommunications wavelength of 1300 nm.
