Abstract
Second harmonic generation can occur in optical fibres illuminated with both an intense pump and a seeding beam at the SH wavelength. The latter is essential but can be provided by an internal seed generated through a quadrupole interaction. This will be discussed below. A comparison of theoretical and experimental results shows that the main contribution is from quadrupole interactions at the core-cladding interface and that the magnitude of the susceptibility is 10-18 esu.
