S. Nitti et al., INDUCED 3RD-ORDER NONLINEARITY VIA CASCADED 2ND-ORDER EFFECTS IN ORGANIC-CRYSTALS OF MBA-NP, Optics communications, 106(4-6), 1994, pp. 263-268
The enhancement of frequency mixing and phase-modulation due to cascad
ed second-order effects is studied in the organic MBA-NP crystal. In a
3 mm-thick sample, we observe a 10(4) increase of the frequency mixin
g yield, which implies an effective 'third-order' susceptibility of 10
(-19) m2/V2.
