Abstract
This paper presents a general description of optical-frequency mixing of n Gaussian laser beams (n=1,2,3,...) with different confocal parameters focused at different positions in the gas medium. A detailed theoretical analysis of third-order sum- and difference-frequency mixing of the light of two laser beams indicates that under certain conditions the output power is enhanced by using unequal confocal beam parameters.Keywords
