SciTech Daily  March 15, 2022 High-harmonic generation has several applications, way to create table-top sources of extreme ultraviolet or x-ray light using lasers, and produce ultrashort light pulses, which are useful for imaging extremely rapid processes such as those that occur in atoms. But high-harmonic generation is inherently difficult to model mathematically, and understand fully. An international team of researchers (Japan, USA – University of Chicago) has developed an analytical approach to high-harmonic generation in the non-perturbative regime using mathematical techniques that had not previously been applied to high-harmonic generation. Their approach revealed the microscopic mechanism that converts incoming intense […]
