Abstract
An investigation is made of the principal characteristics of noncollin ear quasi-phase-matched frequency doubling in the specific case of per iodically polarised lithium niobate. Tn the presence of an instability of the polarisation period, the use of a noncollinear geometry makes it possible to increase the conversion efficiency because of an increa se in the effective interaction length when the incident radiation pro pagates at an acute angle relative to the layers of a nonlinear gratin g.
