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 light into high harmonics and enabled experimental observable to be calculated without the use computers. The research could help shed light on several intriguing experimental results. The same mathematical tool could also be useful in other areas of physics…read more. TECHNICAL ARTICLE
