Abstract :
In this paper, we confirm this interpretation and show that the effect of higher multipoles in SHG is almost completely suppressed when new samples with significantly improved quality are used. Furthermore, we show that the overall SHG response from the new samples is about an order of magnitude higher than from the earlier samples.
