EFFICIENT HARMONIC GENERATION AND FREQUENCY CONVERSION IN MULTI-MODE CAVITIES

摘要

A doubly-resonant cavity structure includes at least one cavity structures so as to allow total frequency conversion for second or third-harmonic generation using ?(2) and ?(3) nonlinearities between the at least one cavity structures. The total frequency conversion is efficiently optimized by determing a critical power allowing for such total frequency conversion to occur depending on the cavity parameters of the at least one cavity structures.
