Nonlinear-Optical studies of organic liquids and polymer optical fibers
The field of experimental nonlinear optics was born with the observation of second harmonic generation by Franken et al. wherein coherent, high-intensity laser light having a center wavelength of 694 nm, impinging on a sample of crystalline quartz produced radiation at twice the frequency (or half the wavelength, i. e., 347 nm) of the incident radiation. Shortly thereafter, observation of a remarkable two-photon process in which radiation incident on an isotropic sample that was seemingly transparent to it produced a fluorescence having a wavelength much shorter than the incident radiation.
