The principle of nonlinear optics
WebbThe phase-matching condition of a nonlinear optical process is a relation among the wavevectors of the interacting waves. When more than two different wavevectors are involved, phase matching can be either collinear or noncollinear, as illustrated in Figure 9-9 (a) and (b) for a second-order process. Webb26 feb. 2024 · We report on a direct generation of efficient and wavelength-tunable third-harmonic generation (THG) from ultrapure electronic-grade (EG) diamond crystals. Under an ultrafast infrared excitation at 1280 nm, the considerably high optical conversion efficiency of ~ 0.7% at a THG wavelength of 427 nm is obtained, and the THG signal can …
