WebThe nonlinear optical properties of essentially nonin teracting molecules in gases were first measured using optical third-harmonic generationl and the Kerr effect.2•a Subsequently dc electric-field induced second-harmonic generation (dcSHG )4-7 became the preferred technique. These data have stimulated theoretical evaluations of the WebApr 10, 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 be tuned …

WebJul 15, 2024 · Optical harmonic generation in gas plasmas has long been studied [1]. A sufficiently strong focused laser pulse leads to air breakdown and air plasma creation, causing pumping beam harmonics in the air plasma. These harmonics are polarized, spectrally narrow, and collinear with the incident pumping beam. WebFeb 10, 2024 · Optical third harmonic generation (THG) is a complicated coherent nonlinear optical process [ 1 ]. In general, nonlinear waves are forbidden for centrosymmetric systems [ 1, 2, 3, 4 ]. However, it is clear that the magnitude of the THG signal is dependent on the specific structure of the sample. how do i end an iphone call
