P. Dietrich et al., HIGH-HARMONIC GENERATION AND CORRELATED 2-ELECTRON MULTIPHOTON IONIZATION WITH ELLIPTICALLY POLARIZED-LIGHT, Physical review. A, 50(5), 1994, pp. 180003585-180003588
The strong ellipticity dependence of correlated two-electron multiphot
on ionization of neon and of the high-harmonic emission from argon (ha
rmonic N=21) and neon (N=41) are reported. These measurements suggest
a common underlying mechanism and are quantitatively consistent with a
recently developed Keldysh-like model of high harmonic generation whi
ch treats the interaction between a newly freed electron and the ion c
ore.
