Origin of strong-field-induced low-order harmonic generation in amorphous quartz
Kerr-type nonlinearities form the basis for our physical understanding of nonlinear optical phenomena in condensed matter, such as self-focusing, solitary waves and wave mixing 1 – 3 . In strong fields, they are complemented by higher-order nonlinearities that enable high-harmonic generation, which...
