摘要: A system for conversion or amplification using quasi-phase matched nonlinear optical wave-mixing is described. The comprises a first radiation source providing pump beam, second signal and bent structure receiving the beam beam. propagation portion of made uniform three-dimensional material at least partly covered by two-dimensional quasi- layer dimension taking into account spatial variation susceptibility along as experienced travelling obtaining in portion. thereby substantially inverse proportional with linear phase mismatch process. also an outcoupling coupling out idler generated structure.
