Abstract

The theory which has been developed to study the effects of higher order nonlinearities in second-order frequency mixing can be applied to the case of up-conversion of high powered lasers. We have considered the effect of the intensity dependence of the refractive index upon phase-matching for second-order frequency mixing. We have also considered the effects of second-order generation on higher-order nonlinearities which have to be considered in the design of other components of high power lasers. This includes the effect of second-order frequency generation on small-scale self-focusing and on the whole beam phase profile.
